Identification
Name: Xanthosine 5-triphosphate
Description: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. 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). It is also a substrate for Xanthine triphosphatase, which is a phosphatase that hydrolyzes non-canonical purine nucleotides such as XTP and ITP to their respective diphosphate derivatives.
