Catalysis of the reaction: S-adenosyl-L-methionine + DNA adenine = S-adenosyl-L-homocysteine + DNA 6-methylaminopurine. Catalysis of the reaction: S-adenosyl-L-methionine + DNA cytosine = S-adenosyl-L-homocysteine + DNA N4-methylcytosine. Catalysis of the reaction: S-adenosyl-L-methionine + DNA containing cytosine = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine. Catalysis of the transfer of a methyl group to a DNA molecule. Catalysis of the transfer of a methyl group to an acceptor molecule. Catalysis of the transfer of a one-carbon group from one compound (donor) to another (acceptor).
