A	deoxycytidylate 5-hydroxymethyltransferase M-CSA #700	Deoxycytidylate (dCMP) 5-hydroxymethylase (CH) of bacteriophage T4 catalyses the addition of a protective hydroxymethyl group to cytosine monophosphate as a method of avoiding digestion by the host restriction systems. It requires the presence of methylenetetrahydrofolate (CH2THF).
