Nucleoside-triphosphate diphosphatase

In enzymology, a nucleoside-triphosphate diphosphatase (EC 3.6.1.19) is an enzyme that catalyzes the chemical reaction a nucleoside triphosphate + H2O a nucleotide + diphosphate Thus, the two substrates of this enzyme are nucleoside triphosphate and H2O, whereas its two products are nucleotide and diphosphate. For example, enzyme deoxyribonucleoside triphosphate pyrophosphatase, encoded by YJR069C in S. cerevisiae and exhibiting (d)ITPase and (d)XTPase activities, hydrolyses ITP, , XTP and releasing pyrophosphate and IMP, dIMP, XMP and , respectively.
