catalytic activity:2 glutathione + H(2)O(2) = glutathione disulfide + 2 H(2)O.,function:Could play a major role in protecting mammals from the toxicity of ingested organic hydroperoxides. Tert-butyl hydroperoxide, cumene hydroperoxide and linoleic acid hydroperoxide but not phosphatidycholine hydroperoxide, can act as acceptors.,similarity:Belongs to the glutathione peroxidase family.,subcellular location:Mainly cytoplasmic.,subunit:Homotetramer.,tissue specificity:Mostly in liver and gastrointestinal tract, not found in heart or kidney.,
Cytoplasm, cytosol .
Mostly in liver and gastrointestinal tract, not found in heart or kidney.
