| guanosine triphosphate | A molecule which consists of the nitrogenous base guanine linked to the sugar ribose and which has three phosphate groups attached to the 5th carbom atom of the ribose. GTP is a high-energy compound which serves as an energy source for many biochemical reactions. It is required for the formation of peptide bonds between amino acids during translation and is required for ribonucleic acid synthesis since it is a direct precursor. (09 Oct 1997) |

| guanosine triphosphate binding protein | <protein> A type of protein embedded in the cytoplasmic membrane of the cell which transmits signals from outside the cell (such as from hormones binding to receptors on the outside of the cell) to the inside of the cell, where it causes some sort of biochemical reaction within the cell to the signal (such as the altering of metabolic pathways or gene expression). The process by which the protein does this is unclear but involves exchanging a molecule of GDP for a molecule of GTP. (09 Oct 1997) |
| phosphomannose isomerase-guanosine diphospho-D-mannose pyrophosphorylase | <chemical> Encoded by alfa gene; from pseudomonas aeruginosa; similar to pssm protein; amino acid sequence given in first source;see also separate records for EC 2.7.7.13 (GDPmannose pyrophosphorylase) and EC 5.3.1.8 (mannosephosphate isomerase) Synonym: pmi-GMP, alga protein (26 Jun 1999) |
| cyclic guanosine monophosphate | A cyclic version of the nucleotide guanosine monophosphate. It plays a role in communicating vision from the eyes to the brain. (09 Oct 1997) |
| tRNA(guanosine-2'-)-methyltransferase | <enzyme> Transfers the methyl group from s-adenosyl-l-methionine to the 2'-hydroxyl group of a guanosine residue present in a gg sequence in trna(try) Registry number: EC 2.1.1.34 Synonym: trna(gm)methylase, trna(wobble guanosine 2'-o-)methyltransferase (26 Jun 1999) |
| U1 small nuclear RNA-(guanosine-N2)-methyltransferase | <enzyme> A trans-active non-small nuclear ribonucleoprotein; facilitates the formation of the m3g cap Registry number: EC 2.1.1.- Synonym: u1 snrna(g-n2)mtase (26 Jun 1999) |
