| crotonase | <enzyme> An enzyme that catalyses reversibly the hydration of unsaturated fatty acyl-CoA to yield beta-hydroxyacyl-CoA. It plays a role in the oxidation of fatty acids and in mitochondrial fatty acid synthesis, has broad specificity, and is most active with crotonyl-CoA. Chemical name: (3S)-3-Hydroxyacyl-CoA hydro-lyase Registry number: EC 4.2.1.17 (12 Dec 1998) |
| crotonic acids | 2-butenoic acids. 4-carbon monounsaturated monocarboxylic acids with the unsaturation in the 2 position. (12 Dec 1998) |
| crotonobetaine reductase | <enzyme> Converts crotonobetaine to gamma-butyrobetaine Registry number: EC 1.3.- (26 Jun 1999) |
| crotonyl-ACP reductase | 1. An enzyme catalyzing hydrogenation of acyl-ACP complexes to 2,3-dehydroacyl-ACP's, with NAD+ as hydrogen acceptor; important in fatty acid metabolism. Synonym: crotonyl-ACP reductase. 2. A variant enzyme has been found carrying out the same reaction as enoyl-ACP reductase, but with NADP+ as hydrogen acceptor. Synonym: acyl-ACP dehydrogenase, acyl-ACP reductase. (05 Mar 2000) |
