| sulfide quinone reductase | <enzyme> Part of the photosynthetic electron transport chain in chlorobium; reaction occurs in the dark, in the absence of oxygen Registry number: EC 1.8.5.- Synonym: plastoquinone reductase, sulfide-quinone oxidoreductase, sqr enzyme, sulfide-quinone reductase (26 Jun 1999) |
|---|
| sodium-translocating NADH-quinone reductase | <enzyme> From vibrio alginolyticus; na+ dependent activation is located in the NADH-quinone reductase segment; reduces ubiquinone-1 to ubisemiquinones or ubiquinol; strongly inhibited by 2-n-heptyl-4-hydroxyquinoline n-oxide; do not confuse with sodium independent NADH-quinone reductase EC 1.6.99.2 Registry number: EC 1.6.5.- Synonym: nqr-1, na-translocating NADH-quinone reductase, nqr gene product (26 Jun 1999) |
|---|---|
| quinone reductase | <enzyme> Enzymes that reduce quinones to phenols usually using NADH or NADPH as a source of reducant. (18 Nov 1997) |
| allyl sulfide | diallyl sulfide; thioallyl ether; oil garlic; a constituent of garlic oil used in the manufacture of flavours. (05 Mar 2000) |
| barium sulfide | A poisonous grayish yellow powder, used as a depilatory. (05 Mar 2000) |
| crude calcium sulfide | Used externally in the treatment of acne, scabies, and ringworm. Synonym: sulfurated lime. (05 Mar 2000) |
| selenium sulfide | A mixture of crystalline selenium monosulfide and solid solutions of selenium and sulfur in an amorphous form, containing 52 to 55.5% Se; used in the treatment of seborrhoea of the scalp or dandruff; it is applied to the scalp as a suspension. (05 Mar 2000) |
| hydrogen sulfide | <chemical> Hydrogen sulfide (h2s). A flammable, poisonous gas with a characteristic odour of rotten eggs. It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. Chemical name: Hydrogen sulfide (H2S) (12 Dec 1998) |
| N-acetyldopamine-quinone isomerase | <enzyme> Enzyme from insect cuticle converts n-acetyldopamine quinone to nada quinone methide Registry number: EC 5.3.2.- Synonym: nada-quinone isomerase (26 Jun 1999) |
| NADPH dehydrogenase (quinone) | A flavoprotein similar to NADH dehydrogenase (quinone), but oxidizing NADPH. Synonym: DT-diaphorase, menadione reductase, phylloquinone reductase, quinone reductase. (05 Mar 2000) |
| NAD(p)h dehydrogenase (quinone) | <enzyme> A flavoprotein that reversibly catalyses the oxidation of NADH or NADPH by various quinones and oxidation-reduction dyes. Since the enzyme is a part of the mitochondrial respiratory chain, defects or deficiencies of this enzyme are an important cause of neurological diseases such as parkinsonism. It may have a protective effect against cancer caused by quinones or their metabolic precursors. The enzyme is inhibited by dicoumarol, capsaicin, and caffeine. Chemical name: NAD(P)H:(quinone-acceptor) oxidoreductase Registry number: EC 1.6.99.2 (12 Dec 1998) |
| sulfide | A compound of sulfur in which the sulfur has a valence of -2; e.g., Na2S, HgS; also, a thioether (i.e., R-S-R', such as lanthionine). Synonym: sulfuret. (05 Mar 2000) |
| sulfide dehydrogenase | <enzyme> From bacteria Registry number: EC 1.8.2.- Synonym: flavocytochrome c, soxb protein, soxb gene product (26 Jun 1999) |
| sulfide oxidase | <enzyme> Catalyses the conversion of hydrogen sulfide to sulfur; isolated from hyphomicrobium neptunium Registry number: EC 1.8.- (26 Jun 1999) |
| di(2-chloroethyl)sulfide | <chemical> 1,1'-thiobis(2-chloroethane). Severe irritant and vesicant of skin, eyes, and lungs. It may cause blindness and lethal lung oedema and was formerly used as a war gas. The substance has been proposed as a cytostatic and for treatment of psoriasis. It has been listed as a known carcinogen in the fourth annual report on carcinogens (ntp-85-002, 1985) (merck, 11th ed). Pharmacological action: carcinogens, chemical warfare agents, dermatologic agents. Chemical name: Ethane, 1,1'-thiobis(2-chloro- (12 Dec 1998) |
| dopa quinone | An oxidation product of dopa and an intermediate in the formation of melanin from tyrosine. (05 Mar 2000) |
