Xanthosine 5-triphosphate

Common 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. 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).

    Enzymes

    General function:
    Involved in hydrolase activity
    Specific function:
    Pyrophosphatase that hydrolyzes the non-canonical purine nucleotides inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) as well as 2-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) and xanthosine 5-triphosphate (XTP) to their respective monophosphate derivatives. The enzyme does not distinguish between the deoxy- and ribose forms. Probably excludes non-canonical purines from RNA and DNA precursor pools, thus preventing their incorporation into RNA and DNA and avoiding chromosomal lesions.
