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