deaminase
A member of the nucleic acid/nucleotide deaminase superfamily prototyped by Neisseria MafB19 [1]. Members of this family are present in a wide phyletic range of bacteria and are predicted to function as toxins in bacterial polymorphic toxin systems [1]. [1]. 21890906.

Cytidine and deoxycytidylate deaminase zinc-binding region
dCMP deaminase family protein
dCMP deaminase family protein such as deoxycytidylate deaminase, which catalyzes the deamination of dCMP to dUMP, providing the nucleotide substrate for thymidylate synthase. The enzyme binds Zn++, which is required for catalytic activity
