UniProt functional annotation for P10486

UniProt code: P10486.

Organism: Escherichia coli.
Taxonomy: Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia.
 
Function: The EcoR124/3 I enzyme recognizes 5'-GAAN(7)RTCG-3'. Subunit R is required for both nuclease and ATPase activities, but not for modification.
 
Catalytic activity: Reaction=Endonucleolytic cleavage of DNA to give random double-stranded fragments with terminal 5'-phosphates, ATP is simultaneously hydrolyzed.; EC=3.1.21.3;
Subunit: The type I restriction/modification system is composed of three polypeptides R, M and S.
Subunit: (Microbial infection) Interacts with Escherichia phage T7 protein Ocr; this interaction leads to the inhibition of the type I bifunctional endonuclease and methyltransferase restriction enzyme R.EcoKI composed of R(2)M(2)S(1). {ECO:0000269|PubMed:32483229}.
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.
Similarity: Belongs to the HsdR family. {ECO:0000305}.
