Accepted name: enzyme-thiol transhydrogenase (glutathione-disulfide)
Reaction: [xanthine dehydrogenase] + glutathione disulfide = [xanthine oxidase] + 2 glutathione
Other name(s): [xanthine-dehydrogenase]:oxidized-glutathione S-oxidoreductase; enzyme-thiol transhydrogenase (oxidized-glutathione); glutathione-dependent thiol:disulfide oxidoreductase; thiol:disulphide oxidoreductase
Systematic name: [xanthine-dehydrogenase]:glutathione-disulfide S-oxidoreductase
Comments: Converts EC xanthine dehydrogenase into EC xanthine oxidase in the presence of glutathione disulfide; also reduces the disulfide bond of ricin. Not inhibited by Cu2+ or thiol reagents.
