Accepted Name
Persulfide dioxygenase.
Alternative Name(s)
Sulfur dioxygenase.
Sulfur oxygenase.
Reaction catalysed
S-sulfanylglutathione + O(2) + H(2)O <=> glutathione + sulfite + 2 H(+)
Cofactor(s)
Fe cation.
Comment(s)
  • Perthiols, formed spontaneously by interactions between thiols and elemental sulfur or sulfide, are the only acceptable substrate to the enzyme.
  • The sulfite that is formed by the enzyme can be further converted into sulfate, thiosulfate or S-sulfoglutathione (GSSO(3)(-)) non- enzymically.
