Systematic name:
NAD+ glycohydrolase (cyclic ADP-ribose-forming)
Reactions
- (1) NAD+ + H2O = ADP-D-ribose + nicotinamide
- (1a) NAD+ = cyclic ADP-ribose + nicotinamide
- (1b) cyclic ADP-ribose + H2O = ADP-D-ribose
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 2.4.99.20, 2'-phospho-ADP-ribosyl cyclase/2'-phospho-cyclic-ADP-ribose transferase. cf. It is also able to act on β-nicotinamide D-ribonucleotide. EC 3.2.2.5, NAD+ glycohydrolase.
