Comments An iron protein. 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 (GSSO3-) non-enzymically [2].
Cofactor Fe cation
History
Reactions S-sulfanylglutathione + O(2) + H(2)O = glutathione + sulfite + 2 H(+).
