Mechanisms of redox-coupled proton transfer in proteins: role of the proximal proline in reactions of the [3Fe-4S] cluster in Azotobacter vinelandii ferredoxin I.
The 7Fe ferredoxin from Azotobacter vinelandii (AvFdI) contains a [3Fe-4S](+/0) cluster that binds a single proton in its reduced level. Although the cluster is buried, and therefore inaccessible to solvent, proton transfer from solvent to the cluster is fast. The kinetics and energetics of the coup...
