ID 1.8.4.7 DE Enzyme-thiol transhydrogenase (glutathione-disulfide). AN [Xanthine-dehydrogenase]:oxidized-glutathione S-oxidoreductase. AN Enzyme-thiol transhydrogenase (oxidized-glutathione). AN Glutathione-dependent thiol:disulfide oxidoreductase. AN Thiol:disulfide oxidoreductase. CA [Xanthine dehydrogenase] + glutathione disulfide = [xanthine oxidase] + CA 2 glutathione. CC -!- Converts EC 1.17.1.4 into EC 1.17.3.2 in the presence of glutathione CC disulfide. CC -!- Also reduces the disulfide bond of ricin. CC -!- Not inhibited by Cu(2+) or thiol reagents. //
