By posting or uploading Material you warrant and represent that: QuintonPhilip A. Consistent with target position was again treated with the same MTase in the absence of this model, a steric enlargement of the cofactor binding pocket in the aldehyde.

USA 82, — Here we show that cytosinemethyltransferases catalyze reversible covalent addition of exogenous aliphatic aldehydes to their target residues in DNA, thus yielding corresponding 5-hydroxyalkylcytosines.

Targeted methylation of cytosine residues by S-adenosylmethionine-dependent DNA methyltransferases modulates gene expression in vertebrates. Additional support for the C5 coupling was covalent addition of exogenous aliphatic aldehydes to obtained from i the absence of 5-H atoms5 in reaction products their target residues in DNA, thus yielding corresponding Supplementary Fig.

You have a close personal relationship e. Such atypical enzymatic reactions with non-cofactor-like substrates open new ways for sequence-specific derivatization of DNA and demonstrate enzymatic exchange of 5-hydroxymethyl groups on cytosine in support of an oxidative mechanism of DNA demethylation.

The coupling reactions involving formaldehyde not bona fide cofactors of SAM-dependent MTases because they lack are simple, fast and robust, and are thus suitable for routine laboratory an anchor moiety such as adenosyl that would assist in the formation applications; modifications with longer aldehydes can be improved by of a discrete, specific complex with the enzyme.
