Nitrogenase employs a sophisticated electron transfer system and a Mo-Fe-S-C cofactor, designated the M-cluster [(cit)MoFe7S9C]), to reduce atmospheric N2 to bioaccessible NH3. Previously, we have shown that the cofactor-free form of nitrogenase can be repurposed as a protein scaffold for the incorporation of a synthetic Fe-S cluster [Fe6S9(SEt)2]4−. Here, we demonstrate the utility of an asymmetric Mo-Fe-S cluster [Cp*MoFe5S9(SH)]3− as an alternative artificial cofactor upon incorporation into the cofactor-free nitrogenase scaffold. The resultant semi-artificial enzyme catalytically reduces C2H2 to C2H4, and CN– into short-chain hydrocarbons, yet it is clearly distinct in activity from its [Fe6S9(SEt)2]4−-reconstituted counterpart, pointing to the possibility to employ molecular design and cluster synthesis strategies to further develop semi-artificial or artificial systems with desired catalytic activities. Incorporation of a synthetic asymmetric Mo-Fe-S cluster, [Cp*MoFe5 S9(SH)] 3−, into the active site of the cofactor-free nitrogenase scaffold results a semi-artificial enzyme that catalytically reduces C2H2 to C2H4, and CN− into short-chain hydrocarbons.
