In enzymology, a NAD+ nucleosidase (EC 3.2.2.5) is an enzyme that catalyzes the chemical reaction
Thus, 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. Other names in common use include NADase, DPNase, DPN hydrolase, NAD hydrolase, diphosphopyridine nucleosidase, nicotinamide adenine dinucleotide nucleosidase, NAD glycohydrolase, NAD nucleosidase, and nicotinamide adenine dinucleotide glycohydrolase. This enzyme participates in nicotinate and nicotinamide metabolism and calcium signaling pathway.
As of late 2007, 25 structures have been solved for this class of enzymes, with PDB accession codes 1ISF, 1ISG, 1ISH, 1ISI, 1ISJ, 1ISM, 1LBE, 1R0S, 1R12, 1R15, 1R16, 1YH3, 1ZVM, 2EF1, 2HCT, 2I65, 2I66, 2I67, 2O3Q, 2O3R, 2O3S, 2O3T, 2O3U, 2PGJ, and 2PGL.
