Protein

Glutathione peroxidase 3

Gene

GPX3

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Protects cells and enzymes from oxidative damage, by catalyzing the reduction of hydrogen peroxide, lipid peroxides and organic hydroperoxide, by glutathione.

Catalytic activityi

2 glutathione + H2O2 = glutathione disulfide + 2 H2O.
