Identification
NameGlutaredoxin-2, mitochondrial
Synonyms
  • Glutathione-dependent oxidoreductase 2
  • Thioltransferase
Gene NameGRX2
Enzyme ClassNot Available
Biological Properties
General FunctionInvolved in electron carrier activity
Specific FunctionMultifunctional enzyme with glutathione-dependent oxidoreductase, glutathione peroxidase and glutathione S- transferase (GST) activity. The disulfide bond functions as an electron carrier in the glutathione-dependent synthesis of deoxyribonucleotides by the enzyme ribonucleotide reductase. In addition, it is also involved in reducing cytosolic protein- and non-protein-disulfides in a coupled system with glutathione reductase. Required for resistance to reactive oxygen species (ROS) by directly reducing hydroperoxides and for the detoxification of ROS-mediated damage
