In enzymology a nucleotide diphosphatase (EC 3.6.1.9) is an enzyme that catalyzes the chemical reactiona dinucleotide + H2O 2 mononucleotidesThus the two substrates of this enzyme are dinucleotide and H2O whereas its product is mononucleotide.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 dinucleotide nucleotidohydrolase.
