Reaction: 2 glutathione + H2O2 = glutathione disulfide + 2 H2O
Other name(s): GSH peroxidase; selenium-glutathione peroxidase; reduced glutathione peroxidase
Systematic name: glutathione:hydrogen-peroxide oxidoreductase
Comments: A protein containing a selenocysteine residue. Steroid and lipid hydroperoxides, but not the product of reaction of EC 18.104.22.168 lipoxygenase on phospholipids, can act as acceptor, but more slowly than H2O2 (cf. EC 22.214.171.124 phospholipid-hydroperoxide glutathione peroxidase).
