SYSTEMATIC NAME
IUBMB Comments
NAD+ glycohydrolase (cyclic ADP-ribose-forming)
This multiunctional enzyme acts on NAD+, catalysing 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. It is also able to act on beta-nicotinamide D-ribonucleotide. cf. EC 3.2.2.5, NAD+ glycohydrolase.
