DE   Sulfur oxygenase/reductase.
AN   Sulfur oxygenase.
AN   Sulfur oxygenase reductase.
CA   4 sulfur + 4 H(2)O + O(2) = 2 H(2)S + 2 HSO(3)(-) + 2 H(+).
CF   Iron.
CC   -!- Elemental sulfur is both the electron donor and one of the two known
CC       acceptors, the other being oxygen.
CC   -!- Another reaction product is thiosulfate, but this is probably formed
CC       non-enzymically at elevated temperature from sulfite and sulfur.
CC   -!- This enzyme differs from EC 1.13.11.18 and EC 1.97.1.3 in that both
CC       activities are found together.
