In enzymology a NMN nucleosidase (EC 3.2.2.14) is an enzyme that catalyzes the chemical reactionnicotinamide D-ribonucleotide + H2O D-ribose 5-phosphate + nicotinamideThus the two substrates of this enzyme are nicotinamide D-ribonucleotide and H2O whereas its two products are D-ribose 5-phosphate and nicotinamide.This enzyme belongs to the family of hydrolases specifically those glycosylases that hydrolyse N-glycosyl compounds.
