Glutathione-dependent oxidoreductase with lower activity compared to the other members of the glutaredoxin family. The disulfide bond functions as an electron carrier in the glutathione-dependent synthesis of deoxyribonucleotides by the enzyme ribonucleotide reductase. Monomer. Strongly induced by the exposure to arsenic which causes glutathione depletion. Present with 573 molecules/cell in log phase SD medium. Belongs to the glutaredoxin family.
