Cluster structure of the mutacin-K8 production system across six S. mutans strains. The ORFs colored in yellow are the possible mutacin-K8 precursor genes. scnGEF: bacteriocin related ABC element; possible immunity system; scnK: histidine kinase of two component system; scnR: response regulator of two component system (Note: mutacin-K8 production system was failed to be identified in S. mutans NCTC 11060, S. mutans ATCC 25175, S. ratti DSM 20564 and S. sobrinus DSM 20742).
