Xanthosine 5-triphosphate
Xanthosine 5-triphosphate (XTP) is a Guanosine triphosphate (GTP) analogue. The base of XTP, xanthine, bears a keto group instead of an amino group at C2 of the purine rings. XTP can substitute for GTP in supporting receptor-mediated adenylyl cyclase activation. XTP competitively inhibits the binding of GTP to the guanine nucleotide-binding site of retinal G-protein, transducin (TD). These suggests that GTP, ITP, and XTP are differential signal sorters and signal amplifiers at the G-protein level. G-proteins mediate signal transfer from receptors to effector systems. (PMID: 9337071). Xanthosine 5-triphosphate is an intermediate of the Purine metabolism pathway, a substrate of the enzymes dinucleoside tetraphosphatase (EC 3.6.1.17) and nucleoside-triphosphate pyrophosphatase (EC 3.6.1.19).
