In

enzymology, a dCTP deaminase (EC 3.5.4.13) is an enzyme that catalyzes the chemical reaction

dCTP + H2O dUTP + NH3

Thus, the two

dCTP and H2O, whereas its two products are dUTP and NH3
.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amidines. The systematic name of this enzyme class is dCTP aminohydrolase. Other names in common use include deoxycytidine triphosphate deaminase, and 5-methyl-dCTP deaminase. This enzyme participates in pyrimidine metabolism.
