Deoxycytidylate Hydroxymethylase (42) - The dCMP hydroxymethylase coded by gene 42 adds a formaldehyde moiety to the S' position of dCMP to yield HMdCMP. This is the first step in. providing a substitute nucleotide triphosphate (HMdCTP). (As mentioned previously, T4 phage DNA requires hydroxymethylcytidine triphosphate (HMdCTP) instead of cytidine triphosphate).
