Sulfur dioxygenase (, sulfur oxygenase, sulfur:oxygen oxidoreductase) is an enzyme with systematic name S-sulfanylglutathione:oxygen oxidoreductase. This enzyme catalyses the following chemical reaction
sulfur + O2 + H2O sulfite + 2 H+ (overall reaction) (1a) glutathione + sulfur S-sulfanylglutathione (spontaneous reaction) (1b) S-sulfanylglutathione + O2 + H2O glutathione + sulfite + 2 H+
This enzyme contains iron.
In humans, sulfur dioxygenase is needed to detoxify sulfide.
