| guanosine 5'-o-(3-thiotriphosphate) | <chemical> Guanosine 5'-(trihydrogen diphosphate), monoanhydride with phosphorothioic acid. A stable GTP analog which enjoys a variety of physiological actions such as stimulation of guanine nucleotide-binding proteins, phosphoinositide hydrolysis, cyclic AMP accumulation, and activation of specific proto-oncogenes. Chemical name: Guanosine 5'-(trihydrogen diphosphate), P'-anhydride with phosphorothioic acid (12 Dec 1998) |
| guanosine 5'-triphosphate | An immediate precursor of guanine nucleotides in RNA; similar to ATP; has a crucial role in microtubule formation. GTP cyclohydrolase, an enzyme that catalyses the reaction of GTP and H2O forming formate and a precursor of tetrahydrobiopterin; a deficiency of this enzyme will result in one form of malignant hyperphenylalaninaemia. Acronym: GTP (05 Mar 2000) |

| guanosine diphosphate | A molecule which consists of the nitrogenous base guanine linked to the sugar ribose and which has two phosphate groups attached to the 5th carbom atom of the ribose. It is a derivative of the ribonucleotide GMP. (09 Oct 1997) |
| guanosine diphosphate fucose | <chemical> A nucleoside diphosphate sugar formed from GDPmannose, which provides fucose for lipopolysaccharides of bacterial cell walls, and for blood group substances and other glycoproteins. Chemical name: Guanosine 5'-(trihydrogen diphosphate), P'-(6-deoxy-beta-L-galactopyranosyl) ester (12 Dec 1998) |
| guanosine diphosphate mannose | <chemical> A nucleoside diphosphate sugar which can be converted to the deoxy sugar GDPfucose, which provides fucose for lipopolysaccharides of bacterial cell walls. Also acts as mannose donor for glycolipid synthesis. Chemical name: Guanosine 5'-(trihydrogen diphosphate), mono-alpha-D-mannopyranosyl ester (12 Dec 1998) |
| guanosine diphosphate sugars | Esters formed between the aldehydic carbon of sugars and the terminal phosphate of guanosine diphosphate. (12 Dec 1998) |
| guanosine monophosphate | A ribonucleotide which consists of the nitrogenous base guanine linked to the sugar ribose and which has a phosphate group attached to the 5th carbon atom of the ribose. (09 Oct 1997) |
| guanosine pentaphosphate | <chemical> Guanosine 5'-triphosphate 2'(3')-diphosphate. A guanine nucleotide containing five phosphate groups. Three phosphate groups are esterified to the sugar moiety in the 5' position and the other two in the 2' or 3' position. This nucleotide serves as a messenger to turn off the synthesis of ribosomal RNA when amino acids are not available for protein synthesis. Synonym: magic spot II. Chemical name: Guanosine 5'-(tetrahydrogen triphosphate), 3'-(trihydrogen diphosphate) (12 Dec 1998) |
| guanosine pentaphosphate synthetase | <enzyme> Also possesses polynucleotide phosphorylase activity; genbank u19858 Registry number: EC 2.7.6.- Synonym: guanosine pentaphosphate synthetase I, gpsi enzyme (26 Jun 1999) |
| guanosine phosphotransferase | <enzyme> From eimeria tenella; uses several phosphate donors: acetyl phosphate, ATP, utp, phosphoribosyl pyrophosphate to form GMP Registry number: EC 2.7.1.- Synonym: gptase (26 Jun 1999) |
| guanosine tetraphosphate | <chemical> Guanosine 5'-diphosphate 2'(3')-diphosphate. A guanine nucleotide containing four phosphate groups. Two phosphate groups are esterified to the sugar moiety in the 5' position and the other two in the 2' or 3' position. This nucleotide serves as a messenger to turn off the synthesis of ribosomal RNA when amino acids are not available for protein synthesis. Synonym: magic spot I. Chemical name: Guanosine 5'-(trihydrogen diphosphate), mono(trihydrogen diphosphate) (ester) (12 Dec 1998) |
