FunFam 318: ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 2

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase. [EC: 3.2.2.6]
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 2.4.99.20.
  • It is also able to act on beta-nicotinamide D-ribonucleotide.
  • Cf. EC 3.2.2.5.
