Accepted name: phospholipid-hydroperoxide glutathione peroxidase
Reaction: 2 glutathione + a hydroperoxy-fatty-acyl-[lipid] = glutathione disulfide + a hydroxy-fatty-acyl-[lipid] + H2O
Other name(s): peroxidation-inhibiting protein; PHGPX; peroxidation-inhibiting protein:peroxidase,glutathione (phospholipid hydroperoxide-reducing); phospholipid hydroperoxide glutathione peroxidase; hydroperoxide glutathione peroxidase
Systematic name: glutathione:lipid-hydroperoxide oxidoreductase
Comments: A protein containing a selenocysteine residue. The products of action of EC lipoxygenase on phospholipids can act as acceptors; H2O2 can also act, but much more slowly (cf. EC glutathione peroxidase).
