Protein

Type I restriction enzyme EcoR124II R protein

Gene

hsdR

Organism
Escherichia coli
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

The EcoR124/3 I enzyme recognizes 5'-GAAN7RTCG-3'. Subunit R is required for both nuclease and ATPase activities, but not for modification.

Catalytic activityi

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

Miscellaneousi

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.
