Glutaredoxin-2

UniProtKB accession:  P17695

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the glutathione system which performs several activities such as glutathione-dependent oxidoreductase, glutathione peroxidase and glutathione S-transferase (GST) activity (PubMed:11875065, PubMed:12684511). 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 (PubMed:9571241, PubMed:18992757, PubMed:20417731). Responsible for the S-glutathionylation of DHBP synthase (PubMed:21565288).
