IUBMB 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. Another reaction product is thiosulfate, but this is probably formed non-enzymically at elevated temperature from sulfite and sulfur . This enzyme differs from EC 1.13.11.18, sulfur dioxygenase and EC 1.12.98.4, sulfur reductase, in that both activities are found together.

The expected taxonomic range for this enzyme is: Archaea, Bacteria
