Enzyme Information

3.5.4.30
dCTP deaminase (dUMP-forming).
based on mapping to UniProt Q9KFV3
dCTP + 2 H(2)O = dUMP + diphosphate + NH(3).
-!- Is highly specific for dCTP as substrate as dCMP, CTP, CDP, CMP, cytosine or deoxycytosine are not deaminated. -!- While most bacteria require two enzymes to form dUMP from dCTP (EC 3.5.4.13 and EC 3.6.1.23), the archaeon Methanocaldococcus jannaschii uses a single enzyme to carry out both functions. -!- This enzyme can also act as a dUTP diphosphatase, but more slowly.
