The maturation of the unique FeMo-cofactor of molybdenum nitrogenase is a multistep process requiring the sequential action of a series of maturase complexes. Here, the authors report on how cryo-electron microscopy structures show NifB-co transfers from NifX to NifEN’s internal site, where NifB-co is converted into FeMo-co for insertion into Mo-nitrogenase.
