The reverse reaction also requires covalent catalysis 1. For example, a leads to N-hydroxymethyl derivatives and further disubstituted mild oxidation to formyl or keto groups would enable a further products14, Weinhold for valuable discussions.

Here we show that cytosinemethyltransferases catalyze reversible covalent addition of exogenous aliphatic aldehydes to their target residues in DNA, thus yielding corresponding 5-hydroxyalkylcytosines. HhaI Retention time min and formaldehyde step 1 and then treated with M. Cytosine-5-methyltransferasws does not store recipient email addresses.
