Glutathione peroxidase (GPx) (EC 1.11.1.9) is the general name of an enzyme family with peroxidase activity whose main biological role is to protect the organism from oxidative damage. The biochemical function of glutathione peroxidase is to reduce lipid hydroperoxides to their corresponding alcohols and … See more Several isozymes are encoded by different genes, which vary in cellular location and substrate specificity. Glutathione peroxidase 1 (GPx1) is the most abundant version, found in the cytoplasm of nearly all mammalian … See more The main reaction that glutathione peroxidase catalyzes is: 2GSH + H2O2 → GS–SG + 2H2O where GSH … See more Mice genetically engineered to lack glutathione peroxidase 1 (Gpx1 mice) are grossly phenotypically normal and have normal lifespans, … See more Activity of glutathione peroxidase is measured spectrophotometrically using several methods.
