In enzymology a NAD+ nucleosidase (EC 3.2.2.5) is an enzyme that catalyzes the chemical reactionNAD+ + H2O ADP-ribose + nicotinamideThus the two substrates of this enzyme are NAD+ and H2O whereas its two products are ADP-ribose and nicotinamide.This enzyme belongs to the family of hydrolases specifically those glycosylases that hydrolyse N-glycosyl compounds. The systematic name of this enzyme class is NAD+ glycohydrolase.
