Metals/Ions

EC Number Metals/Ions Comment Organism Structure
1.12.2.1 Iron the active site is composed of a binuclear Ni-Fe complex bearing three diatomic nonprotein ligands to Fe and three bridges between the two metals, two of which are thiolate side chains of the protein moiety. The third bridging atom in the enzyme is suggested to be sulfur species. The bridging atom is liberated as H2S when the enzyme is reduced under H2 in the presence of its electron carrier cytochrome c3 or methyl viologen Desulfovibrio vulgaris
