Abstract

The core issue: Cofactors in nitrogenases transform dinitrogen into ammonia, and protons into dihydrogen (see scheme). Studies on cuboidal {Fe4S4}2+ and {MoFe3S4}3+ clusters show that Mo clusters are protonated more slowly, but have a higher affinity for binding substrates, than Mo-free clusters. These reactivities explain why the Mo-based nitrogenase is the most efficient at fixing dinitrogen rather than producing dihydrogen.
