(a) X-ray structure of the Desulfovibrio vulgaris Miyazaki F (DvMF) [NiFe]-hydrogenase active site from PDB entry 1WUI (ref. 62). The bridging ligand X is oxygenic for deactivated states, with catalytically active states having either a hydride or a vacant site. (b–d) Some of the structures proposed for isoelectronic Ni-R forms19,20,21,22,23,24,25,26.
