Comments

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