INTRODUCTION

The Center for Protein Engineering (Centre d’Ingénierie des Protéines – CIP) is composed of 6 research teams that comprise 85 members. These teams work in close collaboration to apply their collective knowledge of advanced structural biology, biochemistry, genomics, molecular imaging and microbiology to bacteria and plant models. CIP members are currently exploring the molecular and cellular mechanisms involved in bacterial division and cell wall synthesis, bacterial resistance toward antibiotics, production of cryptic bioactive metabolites, metal homeostasis in plants, alternative splicing mechanisms in plants, folding and misfolding of proteins, and adaptation to extreme environments. Truly efficient research requires access to a broad range of technologies, specific state-of-the-art equipments and expertise. The CIP is also dedicated to the development of technological platforms which aim to: 1) meet the needs of the Center’s scientists; and 2) maintain our strong commitment to support biomedical and biotechnological research in the industrial sector. With the help of the University, we developed the management system of these platforms and are currently developing their technical capabilities in order to provide a spectrum of services ranging from routine assays to specific and customized demands. Furthermore, motivated by our desire to offer a large set of skills to researchers, we constantly adapt and improve networks with other platforms of our institution or in other research institutes. Our ambition is to maintain access to state-of-the-art techniques and equipments to the CIP members and collaborators by maximizing our expertise and insuring a synergic development between platforms. Despite these exciting developments and opportunities, our structure requires a rigorous day-to-day management and ongoing practical respect of the rules we have collegially discussed and approved. The durability of the CIP depends not only on securing subventions, but more importantly on the willingness of all Center’s members to dedicate time and energy to the benefit of all.

Dr Dominique Dehareng left the CIP on July 2014 after more than 28 years of research in the Center. Dominique worked from the start in the unit dedicated to quantum chemistry. She developed expertise in the field of Molecular Mechanics and Molecular Dynamics, both theoretical approaches being used for the conformational studies of peptides, proteins and protein-ligand complexes. Dominique has trained many students in this difficult field, always with enthusiasm and scientific rigor. For several years she was involved in the development of the Master degree in Bio-informatics and Modelling as secretary and, as such, she acted as an interface between the Faculties of Sciences and Applied Sciences of the University.

She was one of the kingpins for the edition of our previous research reports and she also dedicated her time to create the first version of our web site. We were saddened by the death of Georges Dive on June 12th 2014. Georges was one of the founding members of the CIP. He obtained his Master degree in Pharmaceutical Sciences in 1973 and his PhD in 1979. In 1980, he was appointed Chercheur Qualifié (Research Associate) by the FNRS, a permanent position that enabled him to develop his own research group in the CIP. This report describes the major activities of the Center during 2013 and 2014. We hope that it represents a good testimony to the dedication of its members to the initiation of new research lines and to the success of the older ones.

Characterization of Amylolysin, a Novel Lantibiotic from Bacillus amyloliquefaciens GA1 Arguelles Arias A, Ongena M, Devreese B, Terrak M, Joris B and Fickers P PLoS One. 2013 Dec 9; 8(12):e83037 BACKGROUND: Lantibiotics are heat-stable peptides characterized by the presence of thioether amino acid lanthionine and methyllanthionine. They are capable to inhibit the growth of Gram-positive bacteria, including Listeria monocytogenes, Staphylococcus aureus or Bacillus cereus, the causative agents of food-borne diseases or nosocomial infections. Lantibiotic biosynthetic machinery is encoded by gene cluster composed by a structural gene that codes for a pre-lantibiotic peptide and other genes involved in pre-lantibiotic modifications, regulation, export and immunity.

METHODOLOGY/FINDINGS: Bacillus amyloliquefaciens GA1 was found to produce an antimicrobial peptide, named amylolysin, active on an array of Gram-positive bacteria, including methicillin resistant S. aureus. Genome characterization led to the identification of a putative lantibiotic gene cluster that comprises a structural gene (amlA) and genes involved in modification (amlM), transport (amlT), regulation (amlKR) and immunity (amlFE). Disruption of amlA led to loss of biological activity, confirming thus that the identified gene cluster is related to amylolysin synthesis. MALDI-TOF and LC-MS analysis on purified amylolysin demonstrated that this latter corresponds to a novel lantibiotic not described to date. The ability of amylolysin to interact in vitro with the lipid II, the carrier of peptidoglycan monomers across the cytoplasmic membrane and the presence of a unique modification gene suggest that the identified peptide belongs to the group B lantibiotic. Amylolysin immunity seems to be driven by only two AmlF and AmlE proteins, which is uncommon within the Bacillus genus. CONCLUSION/ SIGNIFICANCE: Apart from mersacidin produced by Bacillus amyloliquefaciens strains Y2 and HIL Y-85, 544728, reports on the synthesis of type B-lantibiotic in this species are scarce. This study reports on a genetic and structural characterization of another representative of the type B lantibiotic in B. amyloliquefaciens.

Antimicrobial Activity of Bacillus amyloliquefaciens ANT1 Toward Pathogenic Bacteria and Mold: Effects on Biofilm Arguelles Arias A, Nastro R, Ongena M, Di Costanzo A, Trifuoggi M, Guida M and Fickers P. Probiotics & Antimicro. Prot. 5:252–258, 2013 The intensive use and misuse of antibiotics over the last decades have generated a strong selective pressure for the emergence of multi-resistant strains and nosocomial infections. Biofilm has been demonstrated as a key parameter in spreading infections, especially in hospitals and healthcare units. Therefore, the development of novel anti-biofilm drugs is actually of the upmost importance. Here, the antimicrobial and antibiofilm activities toward pathogenic microorganisms of a set of non-ribosomal synthesized peptides and polyketides isolated from Bacillus amyloliquefaciens ANT1 culture supernatant are presented.

Novel organic solvent-tolerant esterase isolated by metagenomics: insights into the lipase/esterase classification Berlemont R., Spee O., Delsaute M., Lara Y., Schuldes J., Simon C., Power P., Daniel R. and Galleni M. Rev. Argent. Microbiol., 45, 3-12, 2013

In order to isolate novel organic solvent-tolerant (OST) lipases, a metagenomic library was built using DNA derived from a temperate forest soil sample. A two-step activity-based screening allowed the isolation of a lipolytic clone active in the presence of organic solvents. Sequencing of the plasmid pRBest recovered from the positive clone revealed the presence of a putative lipase/esterase encoding gene. The deduced amino acid sequence (RBest1) contains the conserved lipolytic enzyme signature and is related to the previously described OST lipase from Lysinibacillus sphaericus 205y, which is the sole studied prokaryotic enzyme belonging to the 4.4 a/ß hydrolase subgroup (abH04.04). Both in

vivo and in vitro studies of the substrate specificity of RBest1, using triacylglycerols or nitrophenyl-esters, respectively, revealed that the enzyme is highly specific for butyrate (C4) compounds, behaving as an esterase rather than a lipase. The RBest1 esterase was purified and biochemically characterized. The optimal esterase activity was observed at pH 6.5 and at temperatures ranging from 38 to 45°C. Enzymatic activity, determined by hydrolysis of p-nitrophenyl esters, was found to be affected by the presence of different miscible and non-miscible organic solvents, and salts. Noteworthy, RBest1 remains significantly active at high ionic strength. These findings suggest that RBest1 possesses the ability of OST enzymes to molecular adaptation in the presence of organic compounds and resistance of halophilic proteins.

A nanobody binding to non-amyloidogenic regions of the protein human lysozyme enhances partial unfolding but inhibits amyloidfibril formation De Genst E., Chan P-H., Pardon E., Hsu S-T.D., Kumita J.R, Christodoulou R., Menzer L., Chirgadze D.Y, Robinson C.V., Muyldermans S., Matagne A., Wyns L., Dobson C.M., Dumoulin M. J Phys Chem B., 117, 13245-13258, 2013 We report the effects of the interaction of two camelid antibody fragments, generally called nanobodies, namely cAb-HuL5 and a stabilized and more aggregation-resistant variant cAb-HuL5G obtained by protein engineering, on the properties of two amyloidogenic variants of human lysozyme, I56T and D67H, whose deposition in vital organs including the liver, kidney, and spleen is associated with a familial non-neuropathic systemic amyloidosis. Both NMR spectroscopy and X-ray crystallographic studies reveal that cAb-HuL5 binds to the α-domain, one of the two lobes of the native lysozyme structure. The binding of cAb-HuL5/cAb-HuL5G strongly inhibits fibril formation by the amyloidogenic variants; it does not, however, suppress the locally transient cooperative unfolding transitions, characteristic of these variants, in which the β-domain and the C-helix unfold and which represents key early intermediate species in the formation of amyloid fibrils. Therefore, unlike two other nanobodies previously described, cAb-HuL5/cAb-HuL5G does not inhibit fibril formation via the restoration of the global cooperativity of the native structure of the lysozyme variants to that characteristic of the wild-type protein. Instead, it inhibits a subsequent step in the assembly of the fibrils, involving the unfolding and structural reorganization of the α-domain. These results show that nanobodies can protect against the formation of pathogenic aggregates at different stages in the structural transition of a protein from the soluble native state into amyloid fibrils, illustrating their value as structural probes to study the molecular mechanisms of amyloid fibril formation. Combined with their amenability to protein engineering techniques to improve their stability and solubility, these findings support the suggestion that nanobodies can potentially be developed as therapeutics to combat protein misfolding diseases.

Figure: Possible mechanism for lysozyme fibril formation and its inhibition by nanobodies. Partially unfolded intermediate species of the protein (I) in which the C helix and the β-domain are cooperatively unfolded self-associate through the unfolded regions to initiate oligomer formation. This provides a template for the further aggregation of the protein and for the development of the stable, mainly β-sheet, core structure of the protofilaments within an amyloid fibril. The binding of cAb-HuL5 to the loop connecting the A and B helices is likely to inhibit the formation of the first intermolecular interaction (1) or the unfolding and reorganization of the regions of the α-domain that are native-like in the amyloidogenic intermediate (2) but are disorganized in the fibrils. The stage at which aggregation is inhibited by the two nanobodies studied previously, cAb-HuL6 and cAb-HuL22, is also shown for comparison.

Three-dimensional structure of RBcel1, a metagenome-derived psychrotolerant family GH5 endoglucanase Delsaute M., Berlemont R., Dehareng D., Van Elder D., Galleni M., and C. Bauvois Acta Cryst. F69, 828-833 [ doi:10.1107/S1744309113014565 ], 2013 RBcel1 is an endoglucanase belonging to glycoside hydrolase family 5 subfamily 5 (GH5_5) that was recently identified from a soil metagenome library from the Antarctic. Unlike its closest structural homologue (Cel5A from Thermoascus aurantiacus), this enzyme was reported to be able to catalyze transglycosylation reactions and has putatively been implicated in the bacterial cellulose-synthesis process. Here, the structure of RBcel1 at 1.4 Å resolution, solved by molecular replacement, is reported. The structure and putative substrate-binding site are described and compared with those of other GH5_5 subfamily members. PDB reference: 4ee9

The Proline-Rich Motif of the proDer p 3 Allergen Propeptide Is Crucial for Protease-Protease Interaction Dumez ME., Herman J., Campisi V., Bouaziz A., Rosu F., Luxen A., Vandenberghe I., de Pauw E., Frère JM., Matagne A., Chevigné A., and Galleni M. PLOSOne. DOI: 10.1371/journal.pone.0068014, 2013

The majority of proteases are synthesized in an inactive form, termed zymogen, which consists of a propeptide and a protease domain. The propeptide is commonly involved in the correct folding and specific inhibition of the enzyme. The propeptide of the house dust mite allergen Der p 3, NPILPASPNAT, contains a proline-rich motif (PRM), which is unusual for a trypsin-like protease. By truncating the propeptide or replacing one or all of the prolines in the non-glycosylated zymogen with alanine(s), we demonstrated that the full-length propeptide is not required for correct folding and thermal stability and that the PRM is important for the resistance of proDer p 3 to undesired proteolysis when the protein is expressed in Pichia pastoris. Additionally, we followed the maturation time course of proDer p 3 by coupling a quenched-flow assay to mass spectrometry analysis. This approach allowed to monitor the evolution of the different species and to determine the steady-state kinetic parameters for activation of the zymogen by the major allergen Der p 1. This experiment demonstrated that prolines 5 and 8 are crucial for proDer p 3-Der p 1 interaction and for activation of the zymogen.

ProD, D and prop refer to proDer p 3, Der p 3 and propeptide, respectively.

Late Holocene changes in cyanobacterial community structure in maritime Antarctic lakes

R. Fernandez-Carazo, E. Verleyen, D.A. Hodgson, S.J. Roberts, K. Waleron, W. Vyverman and A. Wilmotte J. Paleolimnol., 50, 15-31, 2013 Despite the dominance of cyanobacteria in polar freshwater aquatic ecosystems, little is known about their past biodiversity and response to climate and environmental changes. We explored the use of light microscopy of microfossils, high performance liquid chromatography of the fossil pigment composition and denaturing gradient gel electrophoresis of fossil 16S rRNA genes to study past and present-day differences in cyanobacterial community structure in response to climate changes in two adjacent maritime Antarctic lakes (Beak-1 and Beak-2) with contrasting depths (4 and 26 m) and light climates. Light microscopy was of limited use because of degradation of cell structures. Fossil cyanobacterial pigment concentrations were below the detection limits of our method in several sediment samples in the deep lake, but abundant and diverse in the sediment core from the shallow pond, probably as a consequence of increased light availability and/or a more diverse and abundant benthic cyanobacterial flora. Total carotenoid and chlorophyll concentrations were highest in both lakes between ca. 2,950 and 1,800 cal yr BP, which coincides with the late Holocene climate optimum recognised elsewhere in maritime Antarctica. Cyanobacterial molecular diversity was higher in the top few centimeters of the sediments in both lakes. In deeper sediments, the taxonomic turnover of cyanobacteria appeared to be relatively small in response to past climate anomalies in both lakes, underscoring the broad tolerance of cyanobacteria to environmental variability. This, however, may in part be explained by the low taxonomic resolution obtained with the relatively conserved 16S rRNA gene and/or the preferential preservation of particular taxa. Our results highlight the potential of fossil DNA in lake sediments to study colonization and succession dynamics of lacustrine cyanobacteria and warrant further investigation of the factors that affect preservation of cyanobacterial DNA.

Hard Selective Sweep and Ectopic Gene Conversion in a Gene Cluster Affording Environmental Adaptation M. Hanikenne, J. Kroymann, A. Trampczynska, M. Bernal, P. Motte, S. Clemens, U. Krämer PLoS Genet 9:e1003707. doi:10.1371/journal.pgen.1003707, 2013

Among the rare colonizers of heavy-metal rich toxic soils, Arabidopsis halleri is a compelling model extremophile, physiologically distinct from its sister species A. lyrata, and A. thaliana. Both naturally selected metal hypertolerance and extraordinarily high leaf metal accumulation in A. halleri require Heavy Metal ATPase4 (HMA4) encoding a PIB-type ATPase that pumps Zn2+ and Cd2+ out of specific cell types. Strongly enhanced HMA4 expression results from a combination of gene copy number expansion and cis-regulatory modifications, when compared to A. thaliana. These findings were based on a single accession of A. halleri. Few studies have addressed nucleotide sequence polymorphism at loci known to govern adaptations. We thus sequenced 13 DNA segments across the HMA4 genomic region of multiple A. halleri individuals from diverse habitats. Compared to control loci flanking the three tandem HMA4 gene copies, a gradual depletion of nucleotide sequence diversity and an excess of low-frequency polymorphisms are hallmarks of positive selection in HMA4 promoter regions, culminating at HMA4-3. The accompanying hard selective sweep is segmentally eclipsed as a consequence of recurrent ectopic gene conversion among HMA4 protein-coding sequences, resulting in their concerted evolution. Thus, HMA4 coding sequences exhibit a network-like genealogy and locally enhanced nucleotide sequence diversity within each copy, accompanied by lowered sequence divergence between paralogs in any given individual. Quantitative PCR corroborated that, across A.

halleri, three genomic HMA4 copies generate overall 20- to 130-fold higher transcript levels than in A.

thaliana. Together, our observations constitute an unexpectedly complex profile of polymorphism resulting from natural selection for increased gene product dosage. We propose that these finding are paradigmatic of a category of multi-copy genes from a broad range of organisms. Our results emphasize that enhanced gene product dosage, in addition to neo- and sub-functionalization, can account for the genomic maintenance of gene duplicates underlying environmental adaptation.

Antimicrob Agents Chemother. 57(12): 6358–6360, 2013 β-Lactam antibiotics (penicillins, cephalosporins, carbapenems, and monobactams) represent the most important group of drugs prescribed to treat bacterial infections. They form stable acyl-enzymes with their targets, the membrane-bound DD-transpeptidases, which are essential enzymes in peptidoglycan biosynthesis. These proteins are usually referred to as penicillin-binding proteins (PBPs). The opportunistic human pathogen Enterococcus faecium overproduces the low-affinity PBP5 and mutations within this gene further reduce the acylation rate of PBP5 by altering its amino acid sequence. Ceftaroline is a cephalosporin with broad-spectrum activity against Gram-positive organisms, including methicillin-resistant Staphylococcus aureus (MRSA), and many common Gram-negative bacteria which was recently approved by the U.S. Food and Drug Administration and by the European Medicines Agency (EMA) for similar indications. We have shown that ceftaroline inactivates the low-affinity E. faecium PBP5 more efficiently than benzylpenicillin. It exhibits bacterial killing against our laboratory-derived ampicillin-resistant E. faecium mutant that overproduces the wild-type PBP5.

Figure. Left panel. PBP binding studies for ceftaroline with membrane fractions from D63 and D63r. The concentration of ceftaroline in the competition assay with fluorescent ampicillin is indicated in µg/ml. Right panel. Drug binding studies for ceftaroline with D63 and D63r membrane fractions. MICs of D63 (A) and D63r (B) for ceftaroline were 0.25 mg/liter and 2 mg/liter, respectively. The surviving bacteria were counted after 0, 4, and 24 h of incubation at 37°C by subculturing serial dilutions (at least 10-fold, to minimize drug carryover). For all data, the standard deviations were below 10% of the mean.

Such a profile differs from those of most E. faecium clinical isolates, which were reported resistant to all β-lactams, including ceftaroline. Like other cephalosporins, ceftaroline is not indicated for treatment of enterococcal infections. It is likely that most E. faecium clinical isolates produce mutant PBP5 forms with reduced affinity. This suggests that simple overexpression of wild-type PBP5 is sufficient to moderately increase the MIC for ceftaroline but that amino acid substitutions in the protein are necessary to confer high-level resistance. Among the β-lactams tested to date, ceftaroline has the highest affinity for wild-type PBP5, which makes it a potentially useful tool for PBP5 studies.

The crystal structure of the cell division amidase AmiC reveals the fold of the AMIN domain, a new peptidoglycan binding domain Rocaboy M, Herman R, Sauvage E, Remaut H, Moonens K, Terrak M, Charlier P, Kerff F. Mol Microbiol. 90(2):267-77, 2013 Binary fission is the ultimate step of the prokaryotic cell cycle. In Gram-negative bacteria like Escherichia coli, this step implies the invagination of three biological layers (cytoplasmic membrane, peptidoglycan and outer membrane), biosynthesis of the new poles and eventually, daughter cells separation. The latter requires the coordinated action of the N-acetylmuramyl-L-alanine amidases AmiA/B/C and their LytM activators EnvC and NlpD to cleave the septal peptidoglycan. We present here the 2.5 Å crystal structure of AmiC which includes the first report of an AMIN domain structure, a β-sandwich of two symmetrical four-stranded β-sheets exposing highly conserved motifs on the two outer faces. We show that this N-terminal domain, involved in the localization of AmiC at the division site, is a new peptidoglycan-binding domain. The C-terminal catalytic domain shows an auto-inhibitory alpha helix obstructing the active site. AmiC lacking this helix exhibits by itself an activity comparable to that of the wild type AmiC activated by NlpD. We also demonstrate the interaction between AmiC and NlpD by microscale thermophoresis and confirm the importance of the active site blocking alpha helix in the regulation of the amidase activity. Figure. A. Sequence alignment of the two β-sheets composing the AMIN domain. β-strands are represented by red boxes. Surface residues conserved in the AMIN domains of amidases are highlighted: in yellow, for residues identical in β-sheet1 and β-sheet2 and in blue for residues of similar shape. Residues not conserved in AMIN domains but identical in the two β-sheets are represented in pink. B. Cartoon representation of the AMIN domain. The β-sheet1 (strands β1-2-8-7) and the β-sheet2 (strands β3-4-6-5) are depicted in orange and green respectively. Coils and helix α1 are shown in grey. C.

Allosteric inhibition of VIM metallo-β-lactamases by a camelid nanobody Sohier JS., Laurent C., Chevigné A., Pardon E., Srinivasan V., Wernery U., Lassaux P., Steyaert J., and Galleni M. Biochem. J. 450 ,477–486, doi:10.1042/BJ20121305, 2013

MβL (metallo-β-lactamase) enzymes are usually produced by multi-resistant Gram-negative bacterial strains and have spread worldwide. An approach on the basis of phage display was used to select single-domain antibody fragments (VHHs, also called nanobodies) that would inhibit the clinically relevant VIM (Verona integron-encoded MβL)-4 MβL. Out of more than 50 selected nanobodies, only the NbVIM_38 nanobody inhibited VIM-4. The paratope, inhibition mechanism and epitope of the NbVIM_38 nanobody were then characterized. An alanine scan of the NbVIM_38 paratope showed that its binding was driven by hydrophobic amino acids. The inhibitory concentration was in the micromolar range for all β-lactams tested. In addition, the inhibition was found to follow a mixed hyperbolic profile with a predominantly uncompetitive component. Moreover, substrate inhibition was recorded only after nanobody binding. These kinetic data are indicative of a binding site that is distant from the active site. This finding was confirmed by epitope mapping analysis that was performed using peptides, and which identified two stretches of amino acids in the L6 loop and at the end of the α2 helix. Because this binding site is distant from the active site and alters both the substrate binding and catalytic properties of VIM-4, this nanobody can be considered as an allosteric inhibitor.

Energetics of protein stability at extreme environmental temperatures in bacterial trigger factors

Struvay C, Negro S., Matagne A. and Feller G. Biochemistry 52(17):2982-90, 2013 Trigger factor is the first molecular chaperone interacting co-translationally with virtually all nascent polypeptides synthesized by the ribosome in bacteria. The stability of this primary folding assistant was investigated using trigger factors from the Antarctic psychrophile Pseudoalteromonas

haloplanktis, the mesophile Escherichia coli, and the hyperthermophile Thermotoga maritima. This series covers nearly all temperatures encountered by living organisms. We show that proteins adapt their stability in the whole range of biological temperatures via adjustments of the same fundamental mechanisms, involving increases in enthalpic stabilization and decreases in unfolding rates, in parallel with the environmental temperature. Enthalpic stabilization in trigger factors is characterized by large increases in the melting temperature Tm, ranging from 33°C to 96.6°C, associated with similarly large increases in unfolding enthalpy as revealed by differential scanning calorimetry. Stopped-flow spectroscopy shows that the folding rate constants for the three investigated proteins are similar, whereas the unfolding rate constants differ by several orders of magnitude, revealing that kinetic resistance toward unfolding drives adjustments of protein stability. While the unusual stability of hyperthermophilic proteins has attracted much attention, this study indicates that they are an extreme case of a more general continuum, the other extreme being represented by natively unstable proteins from psychrophiles.

In the hyperthermophilic protein, resistance against unfolding, resulting in slow unfolding kinetics, is the main determinant of its high stability, while fast unfolding is responsible for the low stability of the psychrophilic protein.

Use of Red Autofluorescence for Monitoring Prodiginine Biosynthesis Tenconi E., Guichard P., Motte P., Matagne A., Rigali S. J Microbiol Methods. 2013. 93(2):138-43, 2013 Prodigiosin-like pigments or prodiginines (PdGs) are promising drugs owing to their reported antitumor, antibiotic, and immunosuppressive activities. These natural compounds are produced by several bacteria, including Streptomyces coelicolor and Serratia marcescens as most commonly studied models. The bright red color of these tripyrrole pigments made them excellent reporter molecules for studies aimed at understanding the molecular mechanisms that control secondary metabolite production in microorganisms. However, the natural red fluorescence of PdGs has only been rarely used as a biophysical parameter for detection and assessment of PdG biosynthesis. In this work, we used S. coelicolor in order to exemplify how intrinsic red fluorescence could be utilized for rapid, low-cost, sensitive, specific and accurate semi-quantitative analyses of PdG biosynthesis. Additionally, and contrary to the colorimetric-based approach, the fluorescence-based method allows in situ spatio-temporal visualization of PdG synthesis throughout a solid culture of S. coelicolor. As PdG production is related to cell differentiation, their red autofluorescence could be exploited, by means of confocal microscopy, as a natural marker of the entrance into a crucial developmental stage in the course of the S. coelicolor life cycle

Figures. Left panel: in situ visualization of prodiginine biosynthesis in confluent culture of S. coelicolor.

A Pathway Closely Related to the D-Tagatose Pathway of Gram- Negative Enterobacteria Identified in the Gram-Positive Bacterium Bacillus

licheniformis Van der Heiden E., Delmarcelle M., Lebrun S., Freichels R., Brans A., Vastenavond C., Galleni M., Joris B. Appl Environ Microbiol. 79 (11) : 3511-3515, 2013 We report the first identification of a gene cluster involved in D-tagatose catabolism in Bacillus

licheniformis. The pathway is closely related to the D-tagatose pathway of the Gram-negative bacterium Klebsiella oxytoca, in contrast to the D-tagatose 6-phosphate pathway described in the Gram-positive bacterium Staphylococcus aureus. The functionality of the gene cluster has been demonstrated in E. coli and Bacillus subtilis by supplementation experiments. Pathways for catabolism of galactitol (Gat), D-tagatose (Tag), and lactose (Lac) in different bacteria. In Gram-negative bacteria, such as E. coli or K. oxytoca, galactitol is used as a carbohydrate source and Tag 6-P is an intermediate of the pathway. In K. oxytoca, tagatose is also used as a carbohydrate source by being transported and phosphorylated to yield Tag 1-P. Tag 1,6-BP formed by the tagatose 1-phosphate kinase TagK is further cleaved into DHAP and G3P with the class II tagatose aldolase GatYZ (6). An example of the D-tagatose 6-P pathway of the Gram-positive bacterium S. aureus is shown on the right. In this case, lactose is used as the carbohydrate source and Tag 6-P is an intermediate of the pathway. Glu, D-glucose; Gal, D-galactose. The B. licheniformis PTS-mediated D-tagatose catabolic pathway is related to that of K.oxytoca.

Positive cooperativity between acceptor and donor sites of the peptidoglycan glycosyltransferase Bury D., Dahmane I., Derouaux A., Dumbre S., Herdewijn P., Matagne A., Breukink E. Mueller-Seitz E., Petz P. and Terrak M. Biochem. Pharmacol., 93, 141-150, 2014 The glycosyltransferases of family 51 (GT51) catalyze the polymerization of lipid II to form linear glycan chains, which, after cross linking by the transpeptidases, form the net-like peptidoglycan macromolecule. The essential function of the GT makes it an attractive antimicrobial target; therefore a better understanding of its function and its mechanism of interaction with substrates could help in the design and the development of new antibiotics. In this work, we have used a surface plasmon resonance Biacore(®) biosensor, based on an amine derivative of moenomycin A immobilized on a sensor chip surface, to investigate the mechanism of binding of substrate analogous inhibitors to the GT. Addition of increasing concentrations of moenomycin A to the Staphylococcus aureus MtgA led to reduced binding of the protein to the sensor chip as expected. Remarkably, in the presence of low concentrations of the most active disaccharide inhibitors, binding of MtgA to immobilized moenomycin A was found to increase; in contrast competition with moenomycin A occurred only at high concentrations. This finding suggests that at low concentrations, the lipid II analogs bind to the acceptor site and induce a cooperative binding of moenomycin A to the donor site. Our results constitute the first indication of the existence of a positive cooperativity between the acceptor and the donor sites of peptidoglycan GTs. In addition, our study indicates that a modification of two residues (L119N and F120S) within the hydrophobic region of MtgA can yield monodisperse forms of the protein with apparently no change in its secondary structure content, but this is at the expense of the enzyme function.

Origin and evolution of metal P-type ATPases in Plantae (Archaeplastida) Hanikenne M. and Baurain D. Front Plant Sci, 4:544, 1-15, 2014 Metal ATPases are a subfamily of P-type ATPases involved in the transport of metal cations across biological membranes. They all share an architecture featuring eight transmembrane domains in pairs of two and are found in prokaryotes as well as in a variety of Eukaryotes. In Arabidopsis thaliana, eight metal P-type ATPases have been described, four being specific to copper transport and four displaying a broader metal specificity, including zinc, cadmium and possibly copper and calcium. So far, few efforts have been devoted to elucidating the origin and evolution of these proteins in Eukaryotes. In this work, we used large-scale phylogenetics to show that metal P-type ATPases form a homogenous group among P-type ATPases and that their specialisation into either monovalent (Cu) or divalent (Zn, Cd…) metal transport stems from a gene duplication that took place early in the evolution of Life. Then, we demonstrated that the four subgroups of plant metal ATPases all have a different evolutionary origin and a specific taxonomic distribution, only one tracing back to the cyanobacterial progenitor of the chloroplast. Finally, we examined the subsequent evolution of these proteins in green plants and concluded that the genes thoroughly characterised in model organisms are often the result of lineage-specific gene duplications, which calls for caution when attempting to infer function from sequence similarity alone in non-model organisms.

Phylogeny of IB metal ATPases in prokaryotes and Eukaryotes. The tree was obtained with PhyloBayes (C20 model) from the analysis of a protein alignment of 1761 sequences x 340 AA. Tree branches were coloured based on homogeneous taxonomic composition and collapsed to highlight relationships between prokaryotic and eukaryotic proteins.

Der p 1 is the primary activator of Der p 3, Der p 6 and Der p 9 the proteolytic allergens produced by the house dust mite Dermatophagoides pteronyssinus Herman J., Thelen N., Smargiasso N., Mailleux AC, Luxen A., Cloes M., De Pauw E., Chevigné A., Galleni M., Dumez ME. Biochim Biophys Acta, 1840, 1117-1124, 2014 The enzymatic activity of the four proteases found in the house dust mite Dermatophagoides

pteronyssinus is involved in the pathogenesis of allergy. Our aim was to elucidate the activation cascade of their corresponding precursor forms and particularly to highlight the interconnection between proteases during this cascade. The cleavage of the four peptides corresponding to the mite zymogen activation sites was studied on the basis of the Förster Resonance Energy Transfer method. The proDer p 6 zymogen was then produced in Pichia pastoris to elucidate its activation mechanism by mite proteases, especially Der p 1. The role of the propeptide in the inhibition of the enzymatic activity of Der p 6 was also examined. Finally, the Der p 1 and Der p 6 proteases were localised via immunolocalisation in D. pteronyssinus. All peptides were specifically cleaved by Der p 1, such as proDer p 6. The propeptide of proDer p 6 inhibited the proteolytic activity of Der p 6, but once cleaved, it was degraded by the protease. The Der p 1 and Der p 6 proteases were both localised to the midgut of the mite. Der p 1 in either its recombinant form or in the natural context of house dust mite extracts specifically cleaves all zymogens, thus establishing its role as a major activator of both mite cysteine and serine proteases.

Altered desferrioxamine-mediated iron utilization is a common trait of bald mutants of Streptomyces coelicolor Lambert S., Traxler M., Craig M., Maciejewska M., Ongena M., van Wezel G., Kolter R. and Rigali S. Metallomics, 8, 1390-1399, 2014 Streptomyces coelicolor is an important model organism for developmental studies of filamentous GC-rich actinobacteria. The genetic characterization of mutants of S. coelicolor blocked at the vegetative mycelium stage, the so-called bald (bld) mutants that are unable to erect spore-forming aerial hyphae, has opened the way to discovering the molecular basis of development in actinomycetes. Desferrioxamine (DFO) production and import of ferrioxamines (FO; iron-complexed DFO) are key to triggering morphogenesis of S. coelicolor and we show here that growth of S. coelicolor on the reference medium for Streptomyces developmental studies is fully dependent on DFO biosynthesis. UPLC-ESI-MS analysis revealed that all bld mutants tested are affected in DFO biosynthesis, with bldA, bldJ, and ptsH mutants severely impaired in DFO production, while bldF, bldK, crr and ptsI

mutants overproduce DFO. Morphogenesis of bldK and bldJ mutants was recovered by supplying exogenous iron. Transcript analysis showed that the bldJ mutant is impaired in expression of genes involved in the uptake of FO, whereas transcription of genes involved in both DFO biosynthesis and FO uptake is increased in bldK mutants. Our study allows proposing altered DFO production and/or FO uptake as a novel phenotypic marker of many S. coelicolor bld mutants, and strengthens the role of siderophores and iron acquisition in morphological development of actinomycetes.

Siderophore production is altered in bald mutants. Top: details of bald mutant colonies overlaid with a CAS agar solution to detect the extracellular production of iron-chelating molecules (orange halos).

Control of chitin and N-acetylglucosamine utilization in Saccharopolyspora erythraea

Liao C., Rigali S., Licona Cassani C., Marcellin E., Keld Nielsen L., and Ye BC. Microbiology, 160, 1914-1928, 2014 Chitin degradation and subsequent N-acetylglucosamine (GlcNAc) catabolism is thought to be a common trait of a large majority of actinomycetes. Utilization of aminosugars had been poorly investigated outside the model strain Streptomyces coelicolor A3(2), and we examined here the genetic setting of the erythromycin producer Saccharopolyspora erythraea for GlcNAc and chitin utilization, as well as the transcriptional control thereof. Sacch. erythraea efficiently utilize GlcNAc most likely via the phosphotransferase system (PTSGlcNAc); however, this strain is not able to grow when chitin or N,N'-diacetylchitobiose [(GlcNAc)2] is the sole nutrient source, despite a predicted extensive chitinolytic system (chi genes). The inability of Sacch. erythraea to utilize chitin and (GlcNAc)2 is probably because of the loss of genes encoding the DasABC transporter for (GlcNAc)2 import, and genes for intracellular degradation of (GlcNAc)2 by β-N-acetylglucosaminidases. Transcription analyses revealed that in Sacch. erythraea all putative chi and GlcNAc utilization genes are repressed by DasR, whereas in Strep. coelicolor DasR displayed either activating or repressing functions whether it targets genes involved in the polymer degradation or genes for GlcNAc dimer and monomer utilization, respectively. A transcriptomic analysis further showed that GlcNAc not only activates the transcription of GlcNAc catabolism genes but also activates chi gene expression, as opposed to the previously reported GlcNAc-mediated catabolite repression in Strep. coelicolor. Finally, synteny exploration revealed an identical genetic background for chitin utilization in other rare actinomycetes, which suggests that screening procedures that used only the chitin-based protocol for selective isolation of antibiotic-producing actinomycetes could have missed the isolation of many industrially promising strains.

Crystal structure of penicillin-binding protein 3 (PBP3) from Escherichia coli Sauvage E., Derouaux A., Fraipont C., Joris M., Herman R., Rocaboy M., Schloesser M., Dumas J., Kerff F., Nguyen-Distèche M. and Charlier P. PlosOne, 9, e98042, 2014 In Escherichia coli, penicillin-binding protein 3 (PBP3), also known as FtsI, is a central component of the divisome, catalyzing cross-linking of the cell wall peptidoglycan during cell division. PBP3 is mainly periplasmic, with a 23 residues cytoplasmic tail and a single transmembrane helix. We have solved the crystal structure of a soluble form of PBP3 (PBP357-577) at 2.5 Å revealing the two modules of high molecular weight class B PBPs, a carboxy terminal module exhibiting transpeptidase activity and an amino terminal module of unknown function. To gain additional insight, the PBP3 Val88-Ser165 subdomain (PBP388-165), for which the electron density is poorly defined in the PBP3 crystal, was produced and its structure solved by SAD phasing at 2.1 Å. The structure shows a three dimensional domain swapping with a β-strand of one molecule inserted between two strands of the paired molecule, suggesting a possible role in PBP357-577 dimerization.

Cartoon representation of the crystal structure of PBP3. A ribbon trace of modelled loops undefined in the crystal structure is shown in grey. The active site is indicated by a red sphere. Loops discussed in the text are indicated.

BCCM/ULC: A CULTURE COLLECTION OF (SUB)POLAR

CYANOBACTERIA Since 2005, the BCCM (Belgian Co-ordinated Collections of Microorganisms) has supported the elaboration of a collection of (sub)polar cyanobacteria. The integration towards an official public collection, called BCCM/ULC, has realized in 2011. In 2010, the implementation of a Quality Management System was started and BCCM/ULC has obtained and maintained an ISO9001 certificate for the public deposit and distribution services since 2011. This is a part of the consolidation of the Belgian “Biological Resource Centre (BRC”)”. The BCCM/ULC public collection is now holding over 200 cyanobacterial strains of various origins (freshwater planktonic, terrestrial habitats…) but with a focus on (sub)polar habitats. The catalogue is available on: http:bccm.belspo.be/catalogues/ulc-catalogue-search. It includes 120 (sub)polar unicyanobacterial strains coming from various regions of the Antarctic (South Victoria Land, East Antarctica, Transantarctic Mountains, James Ross Island) and the Arctic (North Canada, Arctic Ocean, Alaska, Svalbard), and different biotopes (microbial mats, lakes, ice shelves, dry valleys, cryptoendoliths, oceans). Twelve strains were isolated in the Sub-Arctic, in Siberian lakes. The most important cyanobacterial orders are represented: Chroococcales, Oscillatoriales, and Nostocales. Moreover, our laboratory is involved in projects for which new isolates are being purified, and will extend the geographic coverage of the collection. The majority of the strains is psychrotolerant and can be cultivated at 18-20°C. They are available as living cultures, and 63 strains also have been cryopreserved (-70°C). A BRAIN-be project to improve the cryopreservation techniques for BCCM/ULC started in 2014 (PRESPHOTO) (www.presphoto.ulg.ac.be). Genomic DNA is available on request. The molecular characterization is underway, on the basis of 16S rRNA and ITS sequences. Exploration of the bioactivities A first screening by Biondi et al. (J. Applied. MIcrobiol., 2008) had already shown the bioactivity of several strains against the bacterium Staphylococcus aureus and the fungi Cryptococcus neoformans. During a bilateral cooperation project with Prof. Fiore (CENA, Piracicaba, Brazil), it was shown with bioassays that the methanol extracts of two strains could inhibit the growth of fungal strains (Candida

kruzeii and Phoma sp.).

HIGH-THROUGHPUT FACILITY

In September 2013, the CIP submitted an application to the DGO6 (Wallonia, Belgium), within the frame of the EQUIP 2013 call. The project (acronym: ROBOTEINE), coordinated by André Matagne, involves two academic partners, namely the CIP and the Structural Biology and Bioinformatics Centre (SBBC, represented by Erik Goormaghtigh) at the Université Libre de Bruxelles (ULB), and an academic associate partner, i.e. the Structural Biology Brussels (SBB, represented by Jan Steyaert) at the Vrije Universiteit Brussel (VUB)/VIB.

Furthermore, the project is supported by three private companies, i.e. Eurogentec, Puratos and Progenosis. The aim of ROBOTEINE is to develop an automated platform for protein production and analysis, on the basis of original high-throughput (HT) methods developed in our laboratories. The project, which has been selected by the DGO6 for funding, started May 1st, 2014. A post-doctoral researcher (Julie Vandenameele) was hired to develop part of the new facility at the CIP. With the help of Alain Brans, Julie is currently developing a platform that offers automated cloning and protein analysis, together with easy colony picking. Furthermore, it allows screening for expression of recombinant proteins in bacteria (both Gram negative and Gram positive) and yeast, and for optimal protein purification. The core of the facility consists of two HT liquid handling devices designed for flexible, fast and accurate sample preparation. Both robotic workstations, which are of the Microlab STAR line by Hamilton, use air displacement pipetting and the unique CO-RE system for forceless tip pickup and ejection. One of these liquid handlers is contained in a sterile housing with a laminar flow of air drawn through a HEPA filter, thus allowing dispensing of sterile liquids for culture media preparation. It is equipped with a high resolution CCD camera and a light table to image colonies, thus allowing fast and economical colony picking. The other liquid handling platform is linked to specialized automated analysis instruments to measure various relevant parameters in the wells (typically 96 or 384 but up to 1536) of microtiter plates. Thus, two microplate readers (Infinite 200 PRO by Tecan) allow UV/Vis absorbance and fluorescence measurements, together with chemiluminescence detection. A system (LabChip GXII) for automated electrophoretic separations of nucleic acids (RNA, DNA) and protein provide fast and easy way to analyze samples across a wide range of molecule and fragment sizes. Finally, an Octet platform allows HT analysis of biomolecular interactions in 96- and 384-well microplates. It enables real-time and label-free determination of affinity, kinetics and concentration and it is thus highly suitable for characterization of drug candidates and development of possible applications. Up to 96 samples can be analyzed in parallel and hence, protein quantitation of 96 samples can be completed in a relatively short time. Rapid kinetics, screening and epitope binding assays are enabled by the multiplexed biosensor formats. Furthermore, proteins can be assayed in crude mixtures such as cell lysates or hybridoma supernatants, glycerol, or in up to 10% DMSO, which drastically reduces sample preparation.

POSTDOCS IN 2013

My name is Sol Schvartzman and I am working in Bioinformatics in the Functional Genomics and

Plant Molecular Imaging laboratory (Plant Biology Institute) with a postdoctoral fellowship since July

2013.

I am originally from Argentina but I lived in Spain most of my life where I studied Biology. I then

moved to Ireland to carry out doctoral studies at the School of Biosystems Engineering at the

University College Dublin. My PhD explored the field of mathematical modeling to predict bacterial

behavior. I worked with Listeria monocytogenes and was interested in finding the combination of

primary and secondary models that would best predict whether Listeria’s populations would grow,

survive or inactivate depending on environmental conditions such as pH, water activity, lactic acid

concentration or temperature. I also did some work on detecting growth/no growth boundaries.

When I finished my PhD I pursued a theoretical MSc in Bioinformatics at the University College Cork

in the south of Ireland.

I am currently working with Arabidopsis halleri, a plant species known to hyperaccumulate Cd and

Zn. This ecotype can be found in sites with contaminated soils but it also lives in healthy grounds. It is

thought that adaptation to contaminated soils may have occurred fairly recently. The objective of my

postdoc is to find genetic determinants of adaptations to high Zn concentrations, and for this I work

with RNA-Seq and epigenetic sequencing data.

Dr Sol Schvartzman Research group: Functional Genomics and Plant Molecular Imaging Project leader: M. Hanikenne

Dr Samir Olatunji Research group: Bacterial diversity, physiology and genetics Project leader: Dr M. Terrak

I did my PhD in Protein Engeneering and Therapeutical Target (October 2009 - March 2013) with Dr

A. Bouhss as Supervisor, in the team of Dr D. Mengin-Lecreux, at the University Paris-Sud 11 in

France. The field of this thesis work was structural and functional studies of MraY, a membrane

protein, member of the polyprenyl-phosphate N-acetylhexosamine 1-phosphate transferase

superfamily, involved in the biosynthesis of bacterial peptidoglycan. On one hand, we have

undertaken the structural characterization of MraY by different biochemical and biophysical

approaches like X-ray crystallography, electron microscopy and small angle X-ray scattering (SAXS).

On the other hand, we have elucidated the catalytic mechanism of this enzyme. In July 2013, I joined

the group of Dr Mohammed Terrak to work on structural characterization of the membrane lipid II

transferase FtsW (production, purification and structure determination) and study of its interactions

with other proteins of the bacterial divisome.

Working in the CIP is an experience both rewarding and enjoyable. It is a pleasant environment with

many helpful and available colleagues. And if occasionally a rain falls on us, because yes, we are in

Belgium, there is certainly a Trappist club or other joy in the Liege city on the horizon to make us feel

on top of the world.

Cyanobacteria produce a range of secondary metabolites. Very little is known about the bioactive

potential and toxicity of cyanobacteria of the Polar Regions where they are the dominant phototrophs

and are exposed to extreme environmental pressure.

In my current research at the CIP, I identify and characterize toxic strains and their secondary

metabolites in one of the largest culture collection of Antarctic cyanobacteria available in the group of

Dr A. Wilmotte or in the BCCM/ULC collection. Various gene clusters involved in secondary

metabolite and toxin production will be investigated. In parallel, extracts are analysed for secondary

metabolites using HPLC and LC-MS. Strains identified as bioactive will be genetically described

using Whole Genome Sequencing and compared with cyanobacteria from other regions. The

identification of geographically separated and genetically different toxin producing cyanobacteria

would give valuable information about the distribution and evolution of cyanobacterial toxicity. We

plan also to study the physiology of the selected organisms and the production of the toxins under

variable parameters such as light, temperature, or nutrient concentrations.

After my graduation in Environmental Toxicology and the completion of my PhD, both at the

University of Konstanz in Germany, I worked at the Natural History Museum in London. In my

previous research I focused on the physiology and toxicology of Arctic and Antarctic cyanobacteria,

but most studies were performed on mixed environmental samples so that an identification of the

toxic/bioactive species was not possible to date. The unialgal cultivation of the respective strains at the

BCCM collection will facilitate detailed genetic, phylogenetic and physiological descriptions.

Newly detected bioactive or cytotoxic compounds may have an application in industrial or medical

services. Furthermore the outcomes of this study would allow the development of functional screening

methods to identify toxin producers in many water bodies worldwide.

POSTDOCS IN 2014

In an interesting turn of events, I am starting in Belgium 2 years later than planned. My position- an

FNRS Chargé de recherche, was awarded in 2012 roughly at the same time that I received an

independent postdoc position at the University of Düsseldorf. Since both positions allowed me to

follow up personally suggested projects I was happy that the FNRS position could be postponed for a

while. I spent 2012-2014 focusing on the nitrogen use efficiency of plants with C3 and C4 type of

photosynthesis using the genus Flaveria that includes species with C3, intermediate and C4

photosynthesis. I analyzed the adaptations to varying nitrogen conditions using proteomics and next

generation sequencing approaches.

I am originally from Macedonia, but most of my scientific experience has been obtained in Germany.

After my PhD at the Max-Planck Institute of Molecular Plant Physiology in Potsdam (Germany),

nutrient sensing and signaling became the main model for studying protein post-translational

modifications as one of the first responses of plants to changing environmental conditions. I find it

intriguing, how a sedentary organism like the plant can adapt and survive in a constantly changing

environment. How information from the plasma membrane is transferred to the nucleus in a cell, or

signals from the root are transferred to the shoot (and vice versa) and as a result the whole organism

changes its behavior: produces more or less sugars, takes up more or less of a specific nutrient or

changes its growth pattern. I want to help determine as many of the molecular mechanisms behind

these sensing/signaling pathways as possible. My hope is that in the long run this work will help in

breeding/producing plants that will need lower amount of fertilizers or grow on poorer soils.

This direction of work also continues at ULg. Here, my main lab is the Functional Genomics and Plant

Molecular Imaging where with Dr Marc Hanikenne we will try to detangle some of the zinc sensing

and signaling pathways in Arabidopsis thaliana. I am co-hosted by the GIGA proteomics lab (Prof. E.

de Pauw) where we will perform the proteomic analyses and look for changes in protein quantities and

phosphorylation. Based on my initial few months, I am looking forward to further work in this

interdisciplinary and international environment.
