Enzyme Information
| 3.5.4.5 |
Cytidine deaminase.
based on mapping to UniProt P0ABF6
(1) Cytidine + H(2)O = uridine + NH(3). (2) 2'-deoxycytidine + H(2)O = 2'-deoxyuridine + NH(3).
-!- Catalyzes the deamination of cytidine and 2'-deoxycytidine with similar efficiencies. -!- The enzyme, which is widely distributed among organisms, is involved in salvage of both exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis. -!- Formerly EC 3.5.4.14.
