Accepted name: glutathione peroxidase
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 lipoxygenase on phospholipids, can act as acceptor, but more slowly than H2O2 (cf. EC phospholipid-hydroperoxide glutathione peroxidase).
