| pyrroline carboxylate reductases | <enzyme> A group of enzymes that catalyze the reduction of 1-pyrroline carboxylate to proline in the presence of NAD(p)h. Includes both the 2-oxidoreductase (ec 1.5.1.1) and the 5-oxidoreductase (ec 1.5.1.2). The former also reduces 1-piperidine-2-carboxylate to pipecolate and the latter also reduces 1-pyrroline-3-hydroxy-5-carboxylate to hydroxyproline. Registry number: EC 1.5.1.- (12 Dec 1998) |
| hydroxymethylglutaryl CoA reductases | <enzyme> In the biosynthesis of cholesterol, these enzymes catalyze the reduction of one of the carboxyl groups of beta-hydroxy, beta-methylglutaryl CoA to yield mevalonic acid.4 requires NADP, EC 1.1.1.88 requires NAD. Chemical name: (S)-Mevalonate:NAD+ oxidoreductase (CoA-acylating) Registry number: EC 1.1.1.88 (12 Dec 1998) |
| nitrite reductases | <enzyme> A group of enzymes that oxidise diverse nitrogenous substances to yield nitrite. Registry number: EC 1. (12 Dec 1998) |
| sulfite reductases | <enzyme> Hydrogen sulfide:(acceptor) oxidoreductases. Enzymes which reversibly catalyze the oxidation of hydrogen sulfide in the presence of various acceptors to sulfite and a reduced acceptor. Utilises NADP+ as the acceptor. Utilises oxidised ferredoxin as acceptor and EC 1.8.99.1 will utilise a variety of acceptors. Registry number: EC 1.8.- (12 Dec 1998) |
| quinone reductases | <enzyme> NAD(p)h:(quinone acceptor) oxidoreductases. A family that includes three enzymes which are distinguished by their sensitivity to various inhibitors. (NAD(p)h dehydrogenase (quinone)) is a flavoprotein which reduces various quinones in the presence of NADH or NADPH and is inhibited by dicoumarol. (NADH dehydrogenase (quinone)) requires NADH, is inhibited by AMP and 2,4-dinitrophenol but not by dicoumarol or folic acid derivatives. (NADPH dehydrogenase (quinone)) requires NADPH and is inhibited by dicoumarol and folic acid derivatives but not by 2,4-dinitrophenol. Registry number: EC 1.6.99. (12 Dec 1998) |
