Enzyme Information

2.1.1.72
Site-specific DNA-methyltransferase (adenine-specific).
based on mapping to UniProt P14385
S-adenosyl-L-methionine + adenine in DNA = S-adenosyl-L-homocysteine + N-6-methyladenine in DNA.
-!- This is a large group of enzymes, most of which form so-called 'restriction-modification systems', with nucleases that possess similar site specificity (the nucleases are listed as either EC 3.1.21.3, EC 3.1.21.4 and EC 3.1.21.5). -!- See the REBASE database for a complete list of these enzymes: http://rebase.neb.com/rebase/
