Reaction: SOD3 catalyzes 2H+ + 2O2.- => O2 + H2O2 (extracellular)
- in pathway: Detoxification of Reactive Oxygen Species
Extracellular Cu-Zn superoxide dismutase (SOD3) catalyzes the reaction of two molecules of superoxide (O2.-) to form one molecule of oxygen (O2) and one molecule of hydrogen peroxide (H2O2) (Marklund et al. 1982, Marklund 1982)
Reaction - small molecule participants:
H2O2 [extracellular region]
O2 [extracellular region]
H+ [extracellular region]
O2.- [extracellular region]
