ABSTRACT

Nitrogenase catalyzes a key step in the global nitrogen cycle, the nucleotide-dependent reduction of atmospheric dinitrogen to bioavailable ammonia. There is a substantial amount of interest in elucidating the biosynthetic mechanisms of the FeMoco and the P-cluster of nitrogenase, because these clusters are not only biologically important but also chemically unprecedented. In this review, we summarize the recent advances in this research area, with an emphasis on our work that aims at providing structural and spectroscopic insights into the assembly of these complex metalloclusters.
