IUBMB Enzyme Nomenclature

EC 3.2.2.5

Accepted name: NAD+ nucleosidase

Reaction: NAD+ + H2O = ADP-ribose + nicotinamide

Other name(s): NADase; DPNase; DPN hydrolase; NAD hydrolase; diphosphopyridine nucleosidase; nicotinamide adenine dinucleotide nucleosidase; NAD glycohydrolase; NAD nucleosidase; nicotinamide adenine dinucleotide glycohydrolase

Systematic name: NAD+ glycohydrolase

Comments: This enzyme can also hydrolyse NADP+ to yield phospho-ADP-ribose and nicotinamide, but more slowly.
