WebThis 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. Webreductase that can catalyze S-denitrosylation reactions. Results TRP14 Is an Efficient L-Cystine Reductase. Like Trx1, TRP14 was earlier shown to be a ubiquitously expressed cytosolic protein (5). Using estimates from immunoblots with recombinant pro-tein standards, we first compared the expression of TRP14 and Trx1 in different cell lines.
