| disulfide | 1. A molecule containing two atoms of sulfur to one of the reference element, e.g., CS2, carbon disulfide. 2. A compound containing the -S-S-group, e.g., cystine. (05 Mar 2000) |
|---|---|
| disulfide bond | A single bond between two sulfurs; specifically, the -S-S- link binding two peptide chains (or different parts of one peptide chain); also occurs as part of the molecule of the amino acid, cystine, and is important as a structural determinant in many protein molecules, notably keratin, insulin, and oxytocin. A symmetric disulfide is R-S-S-R; R'-S-S-R is a mixed disulfide. (05 Mar 2000) |
| disulfide bridge | A disulfide linkage between two cysteinyl residues in a poly-or oligopeptide or in a protein, any disulfide linkage between any thiol-containing moieties of a larger molecule. Synonym: cystine bridge. (05 Mar 2000) |
| disulfides | Chemical groups containing the covalent disulfide bonds -s-s-. The sulfur atoms can be bound to inorganic or organic moieties. (12 Dec 1998) |
| asymmetric disulfide | <chemistry> Disulfide which is not symmetric on both sides of the -s-s- linkage; e.g., the disulfide formed between coenzyme A and glutathione or between cysteine and coenzyme A or glutathione. Synonym: asymmetric disulfide. (05 Mar 2000) |
|---|---|
| carbon disulfide | <chemical> Carbon disulfide (cs2). A colourless, flammable, poisonous liquid, cs2. It is used as a solvent, and is a counterirritant and has local anaesthetic properties but is not used as such. It is highly toxic with pronounced CNS, haematologic, and dermatologic effects. Chemical name: Carbon disulfide (12 Dec 1998) |
| carbon disulfide poisoning | Acute or chronic intoxication by CS2, an industrial condition encountered among rubber workers and makers of artificial silk (rayon) by the viscose process; characterised by insomnia, listlessness, and irritability, followed by paralyses, impaired vision, peptic ulcer, and psychoses. (05 Mar 2000) |
| carbon monoxide dehydrogenase disulfide reductase | <enzyme> Catalyses a reversible exchange of coash with acetyl-CoA in combination with carbon monoxide dehydrogenase (EC 1.2.99.2) Registry number: EC 1.8.- Synonym: co dehydrogenase disulfide reductase, co-dd-reductase (26 Jun 1999) |
| glutathione disulfide | <chemical> A glutathione derivative that forms when the sulfhydryl side chains of the cysteine residues of two glutathione molecules form a disulfide bond during the course of being oxidised with various oxides and peroxides in cells. Glutathione reductase, with the coupled oxidation of NADPH, reduces gssg to two moles of glutathione. Chemical name: Bis(gamma-Glutamyl-L-cysteinylglycine) Disulfide (12 Dec 1998) |
| periplasmic protein disulfide oxidoreductase | <enzyme> Isolated from haemophilus influenzae; may be required for assembly or folding of one or more disulfide-containing cell envelope proteins; ccmg isolated from paracoccus denitrificans Registry number: EC 1.8.4.- Synonym: por disulfide oxidoreductase, por gene product, periplasmic oxidoreductase, ccmg gene product (26 Jun 1999) |
| mixed disulfide | <chemistry> Disulfide which is not symmetric on both sides of the -s-s- linkage; e.g., the disulfide formed between coenzyme A and glutathione or between cysteine and coenzyme A or glutathione. Synonym: asymmetric disulfide. (05 Mar 2000) |
| protein disulfide-isomerase | <enzyme> An enzyme that catalyses the rearrangement of disulfide bonds within proteins during folding. It is a monomer identical to one of the subunits of procollagen-proline dioxygenase. Chemical name: Protein disulfide-isomerase Registry number: EC 5.3.4.1 (12 Dec 1998) |
| protein disulfide reductase (glutathione) | <enzyme> An enzyme that catalyses the reduction of a protein-disulfide in the presence of glutathione, forming a protein-dithiol. Insulin is one of its substrates. Chemical name: Glutathione:protein-disulfide oxidoreductase Registry number: EC 1.8.4.2 (12 Dec 1998) |
| symmetric disulfide | Disulfide that is symmetric on both sides of the -s-s- linkage; i.e., disulfide formed from identical thiol-containing compounds; e.g., cystine, glutathione disulfide. (05 Mar 2000) |
| tetraethylthiuram disulfide | <chemical> A carbamate derivative used as an alcohol deterrent. It is a relatively nontoxic substance when administered alone, but markedly alters the intermediary metabolism of alcohol. When alcohol is ingested after administration of disulfiram, blood acetaldehyde concentrations are increased, followed by flushing, systemic vasodilation, respiratory difficulties, nausea, hypotension, and other symptoms (acetaldehyde syndrome). The intensity and duration of symptoms vary greatly from individual to individual. Pharmacological action: alcohol deterrents. Chemical name: Thioperoxydicarbonic diamide (((H2N)C(S))2S2), tetraethyl- (12 Dec 1998) |
| lipoamide disulfide | Oxidised lipoic acid in amide combination with the &vepsilon;-amino group of an l-lysyl residue of pyruvic acid dehydrogenase. (05 Mar 2000) |
