Type I and II restriction modification (R-M) systems encoded by the B. longum genomes. (A) Alignment of the genomic locations encoding a type I R-M system between B. longum DJO10 and NCC2705. (B) Comparison of a Sau3AI-type II R-M system (recognition site, 5'-GATC-3') with analogous R-M systems in other bacteria and (C) comparison of a EcoRII-type II R-M system (recognition site, 5'-CCWGG-3') with analogous R-M systems in other bacteria. Percentage protein sequence identities compared to B. longum DJO10A are indicated in red.
