Classified as close Interesting Hypothesis 1. Here we show that cytosinemethyltransferases catalyze reversible covalent addition of exogenous aliphatic aldehydes to their target residues in DNA, thus yielding corresponding 5-hydroxyalkylcytosines.

Here we show that cytosinemethyltransferases catalyze reversible covalent addition of exogenous aliphatic aldehydes to their target residues in DNA, thus yielding corresponding 5-hydroxyalkylcytosines. These steric We also examined whether C5-MTases can promote the reverse factors explain the switch in aldehyde regiospecificity in the presence of reaction—the removal of formaldehyde from hmC.
