TRANSCRIPT
Glycogenin: catalyzes glucose transfer from UDP-glucose (red)to tyr194(blue); Mn2+ (green) required to stabilize UDP leaving group
Rabbit muscle Phosphorylase Kinase γ (catalytic) subunit activefragment complexed with ATP and a heptapeptide (RQMSFRL).
As with glycogen phosphorylase:
(a) phosphorylase kinase found in two isoforms in both muscle/liver tissues either active or inactivefor glycogen breakdown
(b) these isoforms differed by phosphorylation
Catalytic (C) subunit of mouse protein kinase A (PKA)complexed with ATP and a peptide inhibitor (Ser→Ala)
Regulatory (R) subunit of bovine protein kinase A (PKA)complexed with 2 cyclic-AMP molecules (activate C*R dissociation)
