ENZYME entry: EC 1.13.11.18

Accepted Name
Sulfur dioxygenase.
Alternative Name(s)
Sulfur oxygenase.
Reaction catalysed
Sulfur + O(2) + H(2)O <=> sulfite + 2 H(+)
Cofactor(s)
Fe cation.
Comment(s)
  • Glutathione (GSH) plays a catalytic role in elemental sulfur activation, but is not consumed during the enzymic reaction.
  • GSH and elemental sulfur react non-enzymically to yield S-sulfanylglutathione and it is only in this form that the sulfur can be oxidized to yield sulfite.
  • The sulfite can be further converted into sulfate, thiosulfate or S-sulfoglutathione (GSSO(3)(-)) non-enzymically.
