Identification
HMDB Protein ID HMDBP00810
Secondary Accession Numbers
  • 6090
Name Epididymal secretory glutathione peroxidase
Synonyms
  1. EGLP
  2. Epididymis-specific glutathione peroxidase-like protein
  3. GPx-5
  4. GSHPx-5
  5. Glutathione peroxidase 5
Gene Name GPX5
Protein Type Enzyme
Biological Properties
General Function Involved in glutathione peroxidase activity
Specific Function Protects cells and enzymes from oxidative damage, by catalyzing the reduction of hydrogen peroxide, lipid peroxides and organic hydroperoxide, by glutathione. May constitute a glutathione peroxidase-like protective system against peroxide damage in sperm membrane lipids.
Pathways
  • Arachidonic acid metabolism
  • Glutathione metabolism
Reactions
Glutathione + Hydrogen peroxide → Oxidized glutathione + Water details
Glutathione + 5(S)-Hydroperoxyeicosatetraenoic acid → Oxidized glutathione + 5-HETE + Water details
