Protein
Glutaredoxin-2, mitochondrial
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Component of the glutathione system which performs several activities such as 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. GRX2 is more active as an oxidoreductase than GRX1.
Similarity
Belongs to the glutaredoxin family.
