Enzyme Commission Primary Name: glutathione amide-dependent peroxidase

Standard Gibbs Free Energy (ΔrG in kcal/mol): -74.20401Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
This enzyme, which has been characterized from the proteobacterium Marichromatium gracile, is a chimeric protein, containing a peroxiredoxin-like N-terminus and a glutaredoxin-like C terminus. The enzyme has peroxidase activity towards hydrogen peroxide and several small alkyl hydroperoxides, and is thought to represent an early adaptation for fighting oxidative stress [Vergauwen01]. The glutathione amide disulfide produced by this enzyme can be restored to glutathione amide by EC 1.8.1.16 (glutathione amide reductase).
