A Tandem Chemoenzymatic Methylation by S‐Adenosyl‐L‐methionine. Issue 8 (6th May 2013) - Lipson, Joseph M.
Abstract Keep ′em methylated: The in situ preparation of the cofactor AdoMet was achieved by allowing the biosynthetic enzyme SalL to operate in the reverse direction by presentation of 5′‐chloro‐5′‐deoxyadenosine at low salt concentrations. This reaction was readily coupled with DNA and small molecule methyltransferases to afford a regioselective method for chemo‐enzymatic methylation and isotope incorporation.
