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.
