the conversion of a thiol into a disulfide occurs by what type of chemical reaction?
coupling of two thiol groups
disulfide









































in chemistry, a disulfide refers to a functional group with the structure r−s−s−r′. the linkage is also called an ss-bond or sometimes a disulfide bridge and is usually derived by the coupling of two thiol groups. in biology, disulfide bridges formed between thiol groups in two cysteine residues are an important component of the secondary and tertiary structure of proteins. the connection is a persulfide, in analogy to its congener, peroxide (r−o−o−r′), but this terminology is rarely used, except in reference to hydrodisulfides (r−s−s−h compounds).

enzyme-thiol transhydrogenase (glutathione-disulfide)









































in enzymology, an enzyme-thiol transhydrogenase (glutathione-disulfide) () is an enzyme that catalyzes the chemical reaction









































thus, the two substrates of this enzyme are xanthine dehydrogenase and glutathione disulfide, whereas its two products are xanthine oxidase and glutathione.









































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 [xanthine-dehydrogenase]:glutathione-disulfide s-oxidoreductase. other names in common use include [xanthine-dehydrogenase]:oxidized-glutathione s-oxidoreductase, enzyme-thiol transhydrogenase (oxidized-glutathione), glutathione-dependent thiol:disulfide oxidoreductase, and thiol:disulfide oxidoreductase. this enzyme participates in glutathione metabolism.
