| 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) |

| glycinamide ribonucleotide | An intermediate in purine biosynthesis, in which the amide N of glycineamide is linked to the C-1 of a ribosyl moiety. (05 Mar 2000) |

| 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) |
| ribonucleotide reductases | <enzyme> Registry number: EC 1.17.4 (12 Dec 1998) |
| 5-aminoimidazole-4-N-succinocarboxamide ribonucleotide | An intermediate in purine biosynthesis. (05 Mar 2000) |
| guanine | <biochemistry, molecular biology> One of the constituent bases of nucleic acids, nucleosides and nucleotides. (18 Nov 1997) |
| guanine aminase | <enzyme> An enzyme that catalyses the deamination of guanine to form xanthine. Chemical name: Guanine aminohydrolase Registry number: EC 3.5.4.3 (12 Dec 1998) |
| guanine cell | A cell whose cytoplasm contains glistening crystals of guanine. (05 Mar 2000) |
| guanine deaminase | <enzyme> An enzyme that catalyses the deamination of guanine to form xanthine. Chemical name: Guanine aminohydrolase Registry number: EC 3.5.4.3 (12 Dec 1998) |
| guanine deoxyribonucleotide | Deoxyguanosine monophosphate, a hydrolysis product of DNA. Synonym: guanine deoxyribonucleotide. (05 Mar 2000) |
| mRNA (guanine(N7))-methyltransferase | <enzyme> Catalyses s-adenosyl-l-methionine and g(5')pppr-RNA to yield s-adenosyl-l-homocysteine and m(7)g(5')pppr-RNA; mRNA containing an n(7)-methylguanine cap Registry number: EC 2.1.1.56 Synonym: mRNA (guanine-7-)methyltransferase, mRNA(guanine-7-)methyltransferase, RNA (guanine-7) methyltransferase, abd1 gene product (26 Jun 1999) |
| pyrimidine-guanine sequence-specific ribonuclease | <enzyme> From yolk granules of adult rana catesbeiana oocytes Registry number: EC 3.1.27.- Synonym: rc-rnase, rana catesbeiana rnase (26 Jun 1999) |
| hypoxanthine-guanine phosphoribosyl tranferase marker | The gene which codes for the enzyme hypoxanthine-guanine phosphoribosyl transferase. It is a selectable marker because cells which have a defective version of this gene are resistant to poisoning by toxic purine derivatives which result from the metabolic pathway that the HGPRT enzyme catalyses. (The purine derivatives are toxic because they incorporate into DNA as a result of the HGPRT enzyme's actions). Because the defective gene cannot produce the enzyme, no toxic purine derivatives are produced, the gene can therefore be selected for. (09 Oct 1997) |
| hypoxanthine guanine phosphoribosyltransferase | <enzyme> An enzyme that catalyses the conversion of 5-phosphoribosyl-1-pyrophosphate and hypoxanthine, guanine, or 6-mercaptopurine to the corresponding 5'-mononucleotides and pyrophosphate. The enzyme is important in purine biosynthesis as well as central nervous system functions. Complete lack of enzyme activity is associated with the lesch-nyhan syndrome, while partial deficiency results in overproduction of uric acid. Chemical name: IMP:pyrophosphate phospho-D-ribosyltransferase Registry number: EC 2.4.2.8 (12 Dec 1998) |
