The miracle of N2ase:How does it do it?
N2 bond energy = 945 kJ/mol!!!!
:N N:
N2 + 8H+ + 8 e- + 16 MgATP 2 NH3 + H2 + 16 MgADP + 16 Pi
Root nodules formedby Rhizobium bacterialiving symbiotically throughnitrogen fixation.
N2 + 8H+ + 8 e- + 16 MgATP 2 NH3 + H2 + 16 MgADP + 16 Pi
EPR used to monitor S= 3/2 signal under a variety of conditions
FeMo protein (FeMoco site) Fe protein
Big Mystery:What is this atom???
P-cluster
Reduced stateOxidized state
Strange Sulfur:CN= 6:Creates flexibility for Fe’s?
