Biosynthesis of the iron-molybdenum cofactor of nitrogenase.

Biosynthesis of the iron-molybdenum cofactor of nitrogenase.

Annual review of microbiology (2008-04-24)

Luis M Rubio, Paul W Ludden

ABSTRACT

The iron-molybdenum cofactor (FeMo-co), located at the active site of the molybdenum nitrogenase, is one of the most complex metal cofactors known to date. During the past several years, an intensive effort has been made to purify the proteins involved in FeMo-co synthesis and incorporation into nitrogenase. This effort is starting to provide insights into the structures of the FeMo-co biosynthetic intermediates and into the biochemical details of FeMo-co synthesis.
