ENZYME entry: EC 2.1.1.72

PURL: https://purl.expasy.org/enzyme/EC/2.1.1.72

Accepted Name

site-specific DNA-methyltransferase (adenine-specific)

Alternative Name(s)

modification methylase, restriction-modification system

N-6 adenine-specific DNA methylase

Reaction catalysed

a 2'-deoxyadenosine in DNA + S-adenosyl-L-methionine = an N(6)-methyl-2'-deoxyadenosine in DNA + S-adenosyl-L-homocysteine + H(+)

Comment(s)

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/
