-
 ?
S-adenosyl-L-methionine + DNA poly(dI-dC) is a better substrate than poly(dG-dC), methylation activity toward unmethylated synthetic as well as native DNA. Activity with hemimethylated DNA is lower than that for unmethylated substrates. Methylation of about 70% of the cytosines in methylatable CpNpN and CpNpG sequences but only 10% in CpG. The enzyme non-selectively methylates any cytosines except in CpG, regardless of the adjacent nucleotide at both 5' and 3' ends Nicotiana tabacum S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine
