Accepted name: ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase
Reaction: NAD+ + H2O = ADP-D-ribose + nicotinamide (overall reaction)
(1a) NAD+ = cyclic ADP-ribose + nicotinamide
(1b) cyclic ADP-ribose + H2O = ADP-D-ribose

Glossary: ADP-D-ribose = adenosine 5′-(5-deoxy-D-ribofuranos-5-yl diphosphate)
cyclic ADP-ribose = N1-(β-D-ribosyl)adenosine 5′(P1),5′′(P2)-cyclic diphosphate
Other name(s): NAD+ nucleosidase; NADase (ambiguous); DPNase (ambiguous); DPN hydrolase (ambiguous); NAD hydrolase (ambiguous); nicotinamide adenine dinucleotide nucleosidase (ambiguous); NAD glycohydrolase (misleading); NAD nucleosidase (ambiguous); nicotinamide adenine dinucleotide glycohydrolase (misleading); CD38 (gene name); BST1 (gene name)
Systematic name: NAD+ glycohydrolase (cyclic ADP-ribose-forming)
Comments: This multiunctional enzyme catalyses both the synthesis and hydrolysis of cyclic ADP-ribose, a calcium messenger that can mobilize intracellular Ca2+ stores and activate Ca2+ influx to regulate a wide range of physiological processes. In addition, the enzyme also catalyses EC, 2′-phospho-ADP-ribosyl cyclase/2′-phospho-cyclic-ADP-ribose transferase. cf. EC, NAD+ glycohydrolase.
