Enzyme Commission Primary Name: phospholipid-hydroperoxide glutathione peroxidase

Enzyme Commission Synonyms: peroxidation-inhibiting protein, PHGPX, peroxidation-inhibiting protein: peroxidase, glutathione (phospholipid hydroperoxide-reducing), phospholipid hydroperoxide glutathione peroxidase, hydroperoxide glutathione peroxidase

Standard Gibbs Free Energy (ΔrG in kcal/mol): -26.941177Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
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).
