WebA low Se intake in dietetically treated patients with phenylketonuria (PKU) or maple syrup urine disease (MSUD) leads to a marked reduction of the platelet glutathione peroxidase activity (GSHPx). 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, indicating this enzyme is not critical for life. However, Gpx1 mice develop cataracts at an early age and exhibit defects in … See more It has been shown that low levels of glutathione peroxidase as measured in the serum may be a contributing factor to vitiligo. Lower plasma glutathione peroxide levels were also observed in patients with type 2 diabetes with macroalbuminuria and this was correlated … See more Mammalian GPx1, GPx2, GPx3, and GPx4 have been shown to be selenium-containing enzymes, whereas GPx6 is a selenoprotein in humans with cysteine-containing homologues in rodents.
