Protein attributes

Sequence length	929 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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.
