Nitrogenase-catalyzed ethane production and CO-sensitive hydrogen evolution from MoFe proteins having amino acid substitutions in an alpha-subunit FeMo cofactor-binding domain.

Abstract excerpt

Unlike wild type, certain Mo-dependent nitrogenases, which are expressed in non-N2-fixing mutant strains of Azotobacter vinelandii and have single amino acid substitutions within a region of the MoFe protein alpha-subunit proposed to encompass an FeMo cofactor-binding domain, are able to catalyze the reduction of acetylene by both two and four electrons to yield ethylene and ethane, respectively (Scott, D. J.,...
