AnfO controls fidelity of nitrogenase FeFe protein maturation by preventing misincorporation of FeV-cofactor.

Based on the heterometal contained within their related active site cofactors, Azotobacter vinelandii produces three genetically distinct, but geometrically and mechanically similar nitrogenase isozymes identified as Mo-dependence, V-dependent, or Fe-only. When compared to the Mo-depend and V-dependent nitrogenases, Fe-only nitrogenase is a poor catalyst for N2 fixation, and it is only available when neither Mo nor V is present. These findings show that AnfO controls the fidelity of Fe-only nitrogenase maturation during the physiological transition from conditions that encourage V-dependent nitrogenase use to Fe-only nitrogenase incorporation to diazotrophic growth, which are interpreted as evidence of diazotrophic growth.
