General annotation (Comments)

Function

Subunit R is required for both nuclease and ATPase activities, but not for modification By similarity.

Catalytic activity

Endonucleolytic cleavage of DNA to give random double-stranded fragments with terminal 5'-phosphates; ATP is simultaneously hydrolyzed.

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 magnesium as cofactors and, in addition to their endonucleolytic and methylase activities, are potent DNA-dependent ATPases By similarity.

Sequence similarities

Belongs to the HsdR family.

Contains 1 helicase ATP-binding domain.
