GTP (also known
as guanylyl imidodiphosphate,
guanosine-5'-triphosphate,
or guanosine triphosphate)
is a chemical compound (nucleotide)
that is incorporated
into the growing RNA chain during synthesis of RNA
and used as a source
of energy during synthesis
of proteins.
GTP is also essential to signal transduction in living cells, where it is converted to GDP through GTPases.
Energy transfer
GTP is involved in energy transfer within the cell. For instance, one GTP molecule is generated for every turn of the Krebs cycle. This is tantamount to the generation of one molecule of ATP since GTP is readilty converted to ATP.
