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