Chemical Information
NameGuanosine triphosphate
DescriptionGuanosine triphosphate, also known as 5'-GTP or H4GTP, belongs to the class of organic compounds known as purine ribonucleoside triphosphates. These are purine ribobucleotides with a triphosphate group linked to the ribose moiety. Thus, a GTP-bound tubulin serves as a cap at the tip of microtubule to protect from depolymerization; and, once the GTP is hydrolyzed, the microtubule begins to depolymerize and shrink rapidly. Guanosine triphosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). Guanosine triphosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine triphosphate is involved in intracellular signalling through adenosine receptor A2B and adenosine. Guanosine-5'-triphosphate (GTP) is a purine nucleoside triphosphate. Outside of the human body, Guanosine triphosphate has been detected, but not quantified in, several different foods, such as mandarin orange (clementine, tangerine), coconuts, new zealand spinachs, sweet marjorams, and pepper (capsicum). This could make guanosine triphosphate a potential biomarker for the consumption of these foods. Cyclic guanosine triphosphate (cGTP) helps cyclic adenosine monophosphate (cAMP) activate cyclic nucleotide-gated ion channels in the olfactory system. It also has the role of a source of energy or an activator of substrates in metabolic reactions, like that of ATP, but more specific. It is used as a source of energy for protein synthesis and gluconeogenesis. For instance, a GTP molecule is generated by one of the enzymes in the citric acid cycle. GTP is also used as an energy source for the translocation of the ribosome towards the 3' end of the mRNA.During microtubule polymerization, each heterodimer formed by an alpha and a beta tubulin molecule carries two GTP molecules, and the GTP is hydrolyzed to GDP when the tubulin dimers are added to the plus end of the growing microtubule. The importing of these proteins plays an important role in several pathways regulated within the mitochondria organelle, such as converting oxaloacetate to phosphoenolpyruvate (PEP) in gluconeogenesis. GTP is involved in energy transfer within the cell.
