[https://www.uniprot.org/uniprot/T1R1_ECOLX T1R1_ECOLX] The restriction (R) subunit of a type I restriction enzyme that recognizes 5'-GAAN(7)RTCG-3' and cleaves a random distance away. Subunit R is required for both nuclease and ATPase activities, but not for modification (Probable) (PubMed:12654995). After locating an unmethylated recognition site, the enzyme complex serves as a molecular motor that translocates DNA in an ATP-dependent manner until a collision occurs that triggers cleavage (Probable). The enzyme undergoes major structural changes to bring the motor domains into contact with DNA, allowing DNA translocation. This prevents DNA access to the catalytic domains of both the R and M subunits, preventing both restriction and methylation (PubMed:32483229).<ref>PMID:32483229</ref> <ref>PMID:12654995</ref> <ref>PMID:2784505</ref> <ref>PMID:32483229</ref>
