| 3-hydroxyacyl CoA dehydrogenases | <enzyme> Enzymes that reversibly catalyze the oxidation of a 3-hydroxyacyl CoA to 3-ketoacyl CoA in the presence of NAD. They are key enzymes in the oxidation of fatty acids and in mitochondrial fatty acid synthesis. Chemical name: (S)-3-Hydroxyacyl-CoA:NAD+ oxidoreductase Registry number: EC 1.1.1.35 (12 Dec 1998) |
|---|---|
| 3-hydroxysteroid dehydrogenases | <enzyme> Catalyze the oxidation of 3-hydroxysteroids to 3-ketosteroids. Registry number: EC 1.1.- (12 Dec 1998) |
| formate dehydrogenases | <enzyme> Flavoproteins that catalyze reversibly the reduction of carbon dioxide to formate. Many compounds can act as acceptors, but the only physiologically active acceptor is NAD. The enzymes are active in the fermentation of sugars and other compounds to carbon dioxide and are the key enzymes in obtaining energy when bacteria are grown on formate as the main carbon source. They have been purified from bovine blood. Chemical name: Formate:NAD+ oxidoreductase Registry number: EC 1.2.1.2 (12 Dec 1998) |
