guanosine triphosphate
guanosine triphosphate n GTP

* * *

(GTP) a nucleotide, the 5′-triphosphate of guanosine; it is an activated precursor in the synthesis of ribonucleic acid and is also involved in energy metabolism, being produced from GDP by substrate level phosphorylation in the tricarboxylic acid (Krebs) cycle and serving as a source of free energy to drive protein synthesis. The ratio of GTP to ATP is maintained by the reversible transfer of phosphate catalyzed by GDP kinase.
