|---|---|
| acetoacetyl-CoA synthetase | <enzyme> Catalyses the conversion of acetoacetate and CoA in the presence of ATP to yield AMP, pyrophosphate and acetoacetyl-CoA; the latter is the first intermediate in cholesterogenesis; also acts more slowly on l-3-hydroxybutanoate Registry number: EC 6.2.1.16 Synonym: acetoacetyl-CoA ligase, acetoacetate-CoA ligase, acetoacetyl-coenzyme a synthetase (26 Jun 1999) |
| acetoacetyl-CoA thiolase | An acetyltransferase forming acetoacetyl-CoA from two molecules of acetyl-CoA, releasing one CoA. A key step in ketogenesis and sterol synthesis. Synonym: acetoacetyl-CoA thiolase, acetyl-CoA thiolase, thiolase. (05 Mar 2000) |
| acetyl-CoA | <enzyme> Condensation product of coenzyme A and acetic acid, symbolised as CoAS~COCH3; intermediate in transfer of two-carbon fragment, notably in its entrance into the tricarboxylic acid cycle and in fatty acid synthesis. This coenzyme plays a huge role in intermediary metabolism, in which cells synthesise, break down or use nutrient molecules for energy production, growth, etc. Acetyl-coenzyme A synthase is found in bacteria and plants and catalyses the reaction in which acetate enters metabolic pathways and forms acetyl-coenzyme A. Synonym: acetyl-coenzyme A, active acetate. (05 Mar 2000) |

| acetyl-CoA acetyltransferase | An acetyltransferase forming acetoacetyl-CoA from two molecules of acetyl-CoA, releasing one CoA. A key step in ketogenesis and sterol synthesis. Synonym: acetoacetyl-CoA thiolase, acetyl-CoA thiolase, thiolase. (05 Mar 2000) |
| acetyl-CoA acylase | <enzyme> An enzyme that catalyses reversibly the hydrolysis of acetyl-CoA to yield CoA and acetate. The enzyme is involved in the oxidation of fatty acids. Chemical name: Acetyl-CoA hydrolase Registry number: EC 3.1.2.1 (12 Dec 1998) |
| acetyl-CoA acyltransferase | <enzyme> An enzyme catalyzing the thioclastic cleavage by coenzyme A of beta-ketoacyl-CoA, forming an acyl-CoA with a carbon chain shorter by two atoms, the missing two atoms appearing as acetyl-CoA. A step in fatty acid degradation. See: acetyl-CoA acetyltransferase. Synonym: 3-ketoacyl-CoA thiolase, beta-ketothiolase. (05 Mar 2000) |
| acetyl-CoA:alpha-glucosaminide acetyltransferase | <enzyme> An enzyme involved in the synthesis of certain carbohydrate moieties on proteins. A deficiency of this enzyme leads to mucopolysaccharidosis type III C. (05 Mar 2000) |
| acetyl CoA-(beta-aminoethyl)-L-cysteine omega-N-acetyltransferase | <enzyme> Forms s-(beta-n-acetyl-aminoethyl)-l-cysteine Registry number: EC 2.3.1.- Synonym: acoac-acetyltransferase, acetyl coenzyme a-(beta-aminoethyl)-l-cysteine omega-n-acetyltransferase (26 Jun 1999) |
| acetyl-CoA c-acetyltransferase | <enzyme> An enzyme that catalyses the reversible formation of acetoacetyl-CoA from two molecules of acetyl-CoA. Chemical name: Acetyl-CoA:acetyl-CoA C-acetyltransferase Registry number: EC 2.3.1.9 (12 Dec 1998) |
| acetyl-CoA c-acyltransferase | <enzyme> Enzyme that catalyses the final step of fatty acid oxidation in which acetyl-CoA is released and the CoA ester of a fatty acid two carbons shorter is formed. Chemical name: Acyl-CoA:acetyl-CoA C-acyltransferase Registry number: EC 2.3.1.16 (12 Dec 1998) |
| acetyl-CoA carboxylase | <enzyme> A carboxylating enzyme that catalyses the conversion of ATP, acetyl-CoA, and hco3- to ADP, orthophosphate, and malonyl-CoA.
