Guanosine triphosphate (GTP) is a purine nucleotide. Its main role is as substrate for the synthesis of RNA during transcription.
It also has the role of a source of energy or an activator of substares in metabolic reactions, like that of ATP, but more specific. It is used as a source of energy for protein synthesis.
GTP is essential to signal transduction, particulary with G-proteins, where it is converted to GDP (guanosine diphosphate) through the action of GTPases.
[edit] Energy transfer
GTP is involved in energy transfer within the cell. For instance, one GTP molecule is generated for every turn of the citric acid cycle. This is tantamount to the generation of one molecule of ATP since GTP is readily converted to ATP.
