Glutathione—cystine transhydrogenase (EC 1.8.4.4) is an enzyme that catalyzes the chemical reaction
The substrates of this enzyme are glutathione and cystine. Its products are glutathione disulfide and cysteine.[1][2]
This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with a disulfide as acceptor. The systematic name of this enzyme class is glutathione:cystine oxidoreductase. Other names in common use include GSH-cystine transhydrogenase, and NADPH-dependent GSH-cystine transhydrogenase. This enzyme participates in cysteine metabolism and glutathione metabolism.
