| ribonucleotide | <biochemistry> A nucleotide in whicha purine or pyrimidine base is linked to a ribose molecule. (09 Oct 1997) |
| ribonucleotide polymerase | <enzyme> DNA-dependent Registry number: EC 2.7.7.- Synonym: oligonucleotide polymerase, decaribonucleotide polymerase (26 Jun 1999) |
| ribonucleotide reductase | A protein complex that converts ribonucleotide diphosphates (NDPs) such as ADP and CDP to 2'-deoxyribonucleotide diphosphates (dNDPs) such as dADP and dCDP. This complex requires thioredoxin, thioredoxin reductase, and NADPH. It is crucial for DNA synthesis. (05 Mar 2000) |
| guanine ribonucleotide | A major component of ribonucleic acids. Synonym: guanine ribonucleotide, guanosine 5'-monophosphate. Guanylic acid reductase (GMP reductase), an enzyme that catalyses the reaction of GMP with NADPH producing IMP, NH3, and NADP+; a part of the purine salvage pathway. Guanylic acid synthetase (GMP synthetase), an enzyme catalyzing the reaction of l-glutamine, XMP, and ATP to produce GMP, l-glutamate, AMP, and pyrophosphate; a key step in purine biosynthesis. Acronym: GMP (05 Mar 2000) |
| 5-aminoimidazole-4-N-succinocarboxamide ribonucleotide | An intermediate in purine biosynthesis. (05 Mar 2000) |
| cytochrome reductases | <enzyme> Registry number: EC 1.6.2. (12 Dec 1998) |
| 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) |
| nitrate reductases | <enzyme> Registry number: EC 1.- (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) |
