| hydrogen-transporting ATP synthase | <enzyme> A group of enzymes which are involved in the reversible synthesis of ATP and that transport protons from the cytoplasmic to the matrix side of the mitochondrial membrane. The flow of protons through the f(0) channel results in ATP synthesis by f1. Chemical name: ATP phosphohydrolase (H+-transporting) Registry number: EC 3.6.1.34 (12 Dec 1998) |
|---|---|
| sulfureted hydrogen | <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) |
| interspecies hydrogen transfer | <biology, ecology> The process in which organic matter is degraded anaerobically by the interaction of several groups of microorganisms in which hydrogen production and hydrogen consumption are closely coupled among species. (09 Oct 1997) |
| 3-chloro-D-alanine hydrogen chloride-lyase | <enzyme> Pseudomonas putida enzyme; forms cysteine from 3-chloro-d-alanine and hydrogen sulfide Registry number: EC 4.5.- Synonym: cahc-lyase, 3-chloro-d-alanine chloride-lyase (deaminating) (26 Jun 1999) |
| formate hydrogen lyase | <enzyme> Consists of EC 1.2.1.2, formate dehydrogenase, plus EC 1.12.1.2, hydrogen dehydrogenase Registry number: EC 1.- Synonym: formate dehydrogenase h, fdhh gene product, fdhf gene product, hyc gene product (26 Jun 1999) |
| acetyl phosphate | CH3CO-OPO32-;a "high energy" phosphate that acts as an acetate donor in the metabolism of various bacteria. Synonym: acetic phosphoric anhydride. (05 Mar 2000) |
| acidulated phosphate fluoride | <chemical> Phosphoric acid, mixt. With sodium fluoride (naf). A sodium fluoride solution, paste or powder, which has been acidulated to pH 3 to 4 and buffered with a phosphate. It is used in the prevention of dental caries. Pharmacological action: fluorides, topical. Chemical name: Phosphoric acid, mixt. With sodium fluoride (NaF) (12 Dec 1998) |
| acyl dihydroxyacetone phosphate oxidoreductase | <enzyme> Forms acyl-sn-glycerol 3-phosphate; uses NADPH Registry number: EC 1.1.1.- (26 Jun 1999) |
| adenosine 3',5'-cyclic phosphate phosphodiesterase | <enzyme> An enzyme that catalyses the hydrolysis of adenosine 3',5'-cyclic phosphate forming 5'-AMP. A crucial step in the regulation of cellular adenosine 3',5'-cyclic phosphate levels. Inhibited by caffeine. Synonym: cAMP phosphodiesterase. (05 Mar 2000) |
| adenosine 3'-phosphate | 3'-Adenylic acid. See: adenylic acid. (05 Mar 2000) |
| adenosine 3'-phosphate 5'-phosphosulfate | 3'-phosphoadenosine 5'-phosphosulfate;an intermediate in the formation of urinary ethereal sulfates, notable for containing a "high energy" sulfate bond; the 3'-OH of adenosine is replaced by -OPO3H2, the 5'-OH by -OP(O2H)-OSO3H. Synonym: active sulfate. Acronym: PAPS (05 Mar 2000) |
| adenosine 5'-phosphate | 5'-Adenylic acid. See: adenylic acid. (05 Mar 2000) |
| adenosine cyclic phosphate | An activator of phosphorylase kinase and an effector of other enzymes, formed in muscle from ATP by adenylate cyclase and broken down to 5'-AMP by a phosphodiesterase; sometimes referred to as the "second messenger." A related compound (2',3') is also known. Synonym: cyclic adenylic acid, cyclic AMP, cyclic phosphate. Acronym: cAMP (05 Mar 2000) |
