Protein Variants | Comment | Organism |
---|---|---|
DELTAC153 | mutation in the MoFe protein of nitrogenase. The rate of oxidation of Fe-protein F1+ to this MoFe protein variant is unchanged from the rate to the wild-type MoFe protein, providing further evidence against a gated hopping electron tansfer model | Azotobacter vinelandii |
S188C | mutation in the MoFe protein of nitrogenase. Electron transfer to the MoFe state that contains P-cluster PN and FeMo-cofactor MN is conformationally gated in both wild-type MoFe and S188C mutant MoFe protein and the amino acid substitution S188C does not alter the conformational gate | Azotobacter vinelandii |

additional information | data support a deficit-spending model of electron transfer where the first event is electron tranfer from the P-cluster to FeMo-cofactor and the second, backfill, event is fast electron tranfer from the Fe protein [4Fe-4S] cluster to the oxidized P-cluster. The first electron transfer is conformationally gated, whereas the second is not | Azotobacter vinelandii | ? | - |
