| 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) |
| ribonucleotide reductases | <enzyme> Registry number: EC 1.17.4 (12 Dec 1998) |
| 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) |
