Accepted name: |
glutathione amide-dependent peroxidase |
Reaction: |
2 glutathione amide + H2O2 = glutathione amide disulfide + 2 H2O |
Systematic name: |
glutathione amide:hydrogen-peroxide oxidoreductase |
Comments: |
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 [1]. The glutathione amide disulfide produced by this enzyme can be restored to glutathione amide by EC 1.8.1.16 (glutathione amide reductase). |
