General annotation (Comments)

Function

Methylation of specific adenine residues; required for both restriction and modification activities By similarity.

Catalytic activity

S-adenosyl-L-methionine + DNA adenine = S-adenosyl-L-homocysteine + DNA 6-methylaminopurine.

Subunit structure

The type I restriction/modification system is composed of three polypeptides R, M and S By similarity.

Miscellaneous

Type I restriction and modification enzymes are complex, multifunctional systems which require ATP, S-adenosyl methionine and Mg2+ as cofactors and, in addition to their endonucleolytic and methylase activities, are potent DNA-dependent ATPases By similarity.

Sequence similarities

Belongs to the N(4)/N(6)-methyltransferase family.
