CC   -!- FUNCTION: The restriction (R) subunit of a type I restriction enzyme
CC       that recognizes an undetermined sequence and cleaves a random distance
CC       away. Subunit R is required for both nuclease and ATPase activities,
CC       but not for modification. After locating a non-methylated recognition
CC       site, the enzyme complex serves as a molecular motor that translocates
CC       DNA in an ATP-dependent manner until a collision occurs that triggers
CC       cleavage. {ECO:0000250|UniProtKB:P08956, ECO:0000303|PubMed:12654995}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage of DNA to give random double-stranded
CC         fragments with terminal 5'-phosphates, ATP is simultaneously
CC         hydrolyzed.; EC=3.1.21.3; Evidence={ECO:0000250|UniProtKB:P08956};
CC   -!- SUBUNIT: The type I restriction/modification system is composed of
CC       three polypeptides R, M and S. {ECO:0000250|UniProtKB:P08956}.
CC   -!- MISCELLANEOUS: Type I restriction and modification enzymes are complex,
CC       multifunctional systems which require ATP, S-adenosyl methionine and
CC       magnesium as cofactors and, in addition to their endonucleolytic and
CC       methylase activities, are potent DNA-dependent ATPases.
CC       {ECO:0000250|UniProtKB:P08956}.
CC   -!- SIMILARITY: Belongs to the HsdR family. {ECO:0000305}.
