Term Name:	NAD+ nucleosidase activity, cyclic ADP-ribose generating
Synonyms:	ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase, NAD hydrolase, NAD(+) nucleosidase, NADase, nicotinamide adenine dinucleotide nucleosidase
Definition:	Catalysis of the reaction: NAD+ + H2O = ADP-D-ribose + nicotinamide + H+, in a two step reaction: first an ADP-ribosyl cyclase reaction to synthesise cyclic ADP-ribose, followed by a cyclic ADP-ribose hydrolase reaction to generate (linear) ADP-ribose.
