Window analysis calculating dN/dS of ssl. dN/dS was calculated as the ratio of nonsynonymous (dN) to synonymous (dS) substitution rates of gene pairs in ssl-12 and Sca_0905 (A), ssl-13 and Sca_0905 (B), and ssl-14 and Sca_0905 (C) from S. aureus and S. carnosus subsp. carnosus genomes. The figure shows only the comparison between N315 (S. aureus) and TM300 (S. carnosus subsp. carnosu). The X-axis represents nucleotide position.
