In enzymology a nucleoside-triphosphatase (EC 3.6.1.15) is an enzyme that catalyzes the chemical reactionNTP + H2O NDP + phosphateThus the two substrates of this enzyme are NTP and H2O whereas its two products are NDP and phosphate.This enzyme belongs to the family of hydrolases specifically those acting on acid anhydrides in phosphorus-containing anhydrides. The systematic name of this enzyme class is unspecific diphosphate phosphohydrolase.
