ID 2.1.1.72 DE site-specific DNA-methyltransferase (adenine-specific). AN modification methylase. AN N-6 adenine-specific DNA methylase. AN restriction-modification system. CA a 2'-deoxyadenosine in DNA + S-adenosyl-L-methionine = an N(6)-methyl- CA 2'-deoxyadenosine in DNA + H(+) + S-adenosyl-L-homocysteine. CC -!- This is a large group of enzymes, most of which form so-called CC 'restriction-modification systems', with nucleases that possess CC similar site specificity (the nucleases are listed as either CC EC 3.1.21.3, EC 3.1.21.4 and EC 3.1.21.5).
