Fig. 1. Color-coded Cas genes of strains according to types/subtypes, direction of loci, and localization of anti-repeat sequences on CRISPR loci of strains. Anti-repeat sequences are located in three regions of CRISPR loci, i) upstream or downstream of the repeat-spacer array, ii) upstream of the Cas9 chromosome, and iii) in the area between Cas9 and Cas1. 100% of anti-repeat sequences were located between Cas1 and Cas9 while 3 strains had a second anti-repeat sequence at downstream region of repeat-spacer array.
