The Biosynthesis and Function of Nitrogenase Metalloclusters
… of N2 to ammonia (nitrogen fixation). The metalloclusters associated with the nitrogenase components include the [4Fe-4S] cluster of the Fe protein, and the P-cluster [8Fe7S] and FeMo-cofactor [7Fe-9S-Mo-X-homocitrate], both contained within the MoFe protein. These metal-complexes play a …

Coordination Chemistry of Fe–S Clusters Supported by N-Heterocyclic Carbenes
… by poor control over the coordination sphere of metalloclusters as compared to mononuclear complexes: the large size of metalloclusters means changing the ligand at one metal site often has little effect on the neighboring sites. Here, we introduce a strategy based on the remote steric profiles …

Studies on the structure and function of various nif and nif- associated gene products encoded within the Azotobacter vinelandii nif gene cluster
… the structural and functional roles of the metalloclusters present within the MoFe protein of nitrogenase from Azotobacter vinelandii. A gene replacement strategy was developed for oligonucleotide-directed mutagenesis of these proteins and the resulting biological and biochemical effects of …

Metallocluster Site-Differentiation and Subsite Specific Heterometal Substitution
The deployment of metalloclusters in applications such as catalysis and materials synthesis requires robust methods for site-differentiation: the conversion of clusters with symmetric ligand spheres to those with unsymmetrical ligand spheres. However, imparting precise patterns of …
