IUBMB Comments
gamma-glutamylcysteine:NADP+ oxidoreductase
Contains FAD. The enzyme, which is found only in halobacteria, maintains the concentration of gamma-glutamylcysteine, the major low molecular weight thiol in halobacteria. Not identical with EC 1.8.1.7 (glutathione-disulfide reductase) or EC 1.8.1.14 (CoA-disulfide reductase).
