Abstract excerpt

Iron-molybdenum cofactor (FeMo-co) biosynthesis involves the participation of several proteins. We have used (55)Fe-labeled NifB-co, the specific iron and sulfur donor to FeMo-co, to investigate the accumulation of protein-bound precursors of FeMo-co. The (55)Fe label from radiolabeled NifB-co became associated with two major protein bands when the in vitro FeMo-co synthesis reaction was carried out with the...
