Sulfur_dioxygenase
Sulfur dioxygenase (EC 1.13.11.18, sulfur oxygenase, sulfur:oxygen oxidoreductase) is an enzyme with systematic name S-sulfanylglutathione:oxygen oxidoreductase.[1][2] 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.[3]
