A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

Accepted Name
ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase.
Alternative Name(s)
NAD hydrolase.
NAD(+) nucleosidase.
Nicotinamide adenine dinucleotide nucleosidase.
Reaction catalysed
NAD(+) + H(2)O <=> ADP-D-ribose + nicotinamide
  • This multiunctional enzyme catalyzes both the synthesis and hydrolysis of cyclic ADP-ribose, a calcium messenger that can mobilize intracellular Ca(2+) stores and activate Ca(2+) influx to regulate a wide range of physiological processes.
  • In addition, the enzyme also catalyzes EC
  • It is also able to act on beta-nicotinamide D-ribonucleotide.
  • Cf. EC
