This is the C-terminal domain of Type ISP restriction-modification enzyme LLaBIII present in Lactococcus lactis subsp. cremoris. Type ISP restriction-modification (RM) enzymes provide a potent defence against infection by foreign and bacteriophage DNA. This domain interacts extensively with DNA and is known as the target recognition domain (TRD). TRD works by recognising 6/7 base pairs of asymmetric sequence [1].	Domain

Type ISP restriction-modification (RM) enzymes cleave random DNA between distant target sites when two enzymes collide following convergent ATP-driven translocation. This entry represents the all-helical coupler domain of type ISP RM enzymes, which links the ATPase to the MTase and the C-terminal TRD (target recognition domain) domains and seems to play a key role in transferring conformational strain during initiation [1-3].
