DCTD (deoxycytidylate deaminase), also known as dCMP deaminase, is a 178aa allosteric enzyme that exists as a homohexamer and belongs to the cytidine and deoxycytidylate deaminase protein family. using zinc as a cofactor, DCTD catalyzes the deamination of dCMP to duMP, thereby producing the nucleotide substrate (duMP) that is used by thymidylate synthase. Source: Recombinant protein corresponding to aa1-178 of human DCTD, fused to His-tag at N-terminal expressed in E. coli.
