Comments

FUNCTION: Protects cells and enzymes from oxidative damage, by catalyzing the reduction of hydrogen peroxide, lipid peroxides and organic hydroperoxide, by glutathione.
CATALYTIC ACTIVITY: 2 glutathione + H₂O₂ = glutathione disulfide + 2 H₂O.
SUBUNIT: Homotetramer.
SUBCELLULAR LOCATION: Secreted.
TISSUE SPECIFICITY: Secreted in plasma.
SIMILARITY: Belongs to the glutathione peroxidase family.
