S-adenosyl-L-methionine + DNA adenine | the enzyme methylates adenines at the N6 position of palindromic 5-GATC-3 sites. The enzyme ethylates both strands of the same site prior to fully dissociating from the DNA, a process referred to as intrasite processivity. Intrasite processivity is disrupted when the DNA flanking a single GATC site is longer than 400 bp on either side. The introduction of a second GATC site within this flanking DNA reinstates intrasite methylation of both sites | Escherichia coli | S-adenosyl-L-homocysteine + DNA 6-methyladenine | - |
