CAS Registry Number
Comments This enzyme, which is found in thermophilic microorganisms, contains one mononuclear none-heme iron centre per subunit. Elemental sulfur is both the electron donor and one of the two known acceptors, the other being oxygen. Thiosulfate is also observed as a product, but is likely formed non-enzymically by a reaction between sulfite and sulfur [1]. This enzyme differs from EC 1.13.11.18, sulfur dioxygenase and EC 1.12.98.4, sulfhydrogenase, in that both activities occur simultaneously.
Cofactor Fe cation
History
Reactions 4 sulfur + 4 H(2)O + O(2) = 2 H(2)S + 2 HSO(3)(-) + 2 H(+).
