||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 . This enzyme differs from EC 18.104.22.168, sulfur dioxygenase and EC 22.214.171.124, sulfhydrogenase, in that both activities occur simultaneously.
