Guanosine-5'-triphosphate, a purine nucleotide, is required as a coenzyme for protein biosynthesis in a cell-free system. Guanosine 5′-triphosphate (GTP), a purine trinucleotide, is a substrate for RNA polymerases and a wide range of GTPase including G-protein coupled receptor (GPCR)…

Guanosine 5'-triphosphate (GTP), a purine trinucleotide, is a substrate for RNA polymerases and a wide range of GTPase including G-protein coupled receptor (GPCR) GTPases and cell signaling and cycling associated guanine nucleotide exhange factors (GEF).

GTP functions as a carrier of phosphates and pyrophosphates involved in channeling chemical energy into specific biosynthetic pathways. GTP activates the signal transducing G proteins which are involved in various cellular processes including proliferation, differentiation, and activation of…
