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 + a lipid hydroperoxide =
CC       glutathione disulfide + lipid + 2 H(2)O.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (Potential).
CC   -!- SIMILARITY: Belongs to the glutathione peroxidase family.
