  1. The miracle of N2ase: How does it do it? :N N: N2 bond energy = 945 kJ/mol!!!! N2 + 8H+ + 8 e- + 16 MgATP 2 NH3 + H2 + 16 MgADP + 16 Pi

  2. Root nodules formed by Rhizobium bacteria living symbiotically through nitrogen fixation.

  3. N2 + 8H+ + 8 e- + 16 MgATP 2 NH3 + H2 + 16 MgADP + 16 Pi

  4. EPR used to monitor S= 3/2 signal under a variety of conditions FeMo protein (FeMoco site) Fe protein

  5. Big Mystery: What is this atom???

  6. P-cluster Oxidized state Reduced state Strange Sulfur: CN= 6: Creates flexibility for Fe’s?
