DCTP diphosphatase

In enzymology, a dCTP diphosphatase (EC 3.6.1.12) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are dCTP and H₂O, whereas its two products are dCMP and diphosphate.

This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides in phosphorus-containing anhydrides. The systematic name of this enzyme class is dCTP nucleotidohydrolase. Other names in common use include deoxycytidine-triphosphatase, dCTPase, dCTP pyrophosphatase, deoxycytidine triphosphatase, deoxy-CTPase, and dCTPase. This enzyme participates in pyrimidine metabolism.
