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 (By similarity).
CC   -!- TISSUE SPECIFICITY: Secreted in plasma.
CC   -!- SIMILARITY: Belongs to the glutathione peroxidase family.
