Abstract
Based on model experiments it is suggested that the reduction of subst rates by nitrogenase occurs at a mononuclear site containing molybdenu m, homocitrate and the imidazole component of his-442 of the apoenzyme , generated from the FeMo-co by a reversible dissociation of the Fe7S8 unit from the MoFe7S8 cluster in a redox-linked process.
