2DPM - PubMed Abstract: 
. Methyltransferases (Mtases) catalyze the transfer of methyl groups from S-adenosylmethionine (AdoMet) to a variety of small molecular and macromolecular substrates. These enzymes contain a characteristic alpha/beta structural fold. Four groups of DNA Mtases have been defined and representative structures have been determined for three groups. DpnM is a DNA Mtase that acts on adenine N6 in the sequence GATC; the enzyme represents group alpha DNA Mtases, for which no structures are known.
