Circular representation of the S. pyogenes chromosome

Circular map of GAS strain SSI-1. The outer circle shows the scale (bp). Ring 1 and 2 show the coding sequence by strands (ring 1, clockwise; ring 2, counterclockwise). The predicted ORFs are distinguished with different colors in COG classification. Ring 3 shows the genes for bacteriophage (pink), Transposase genes and insertion sequence (black), adhesive molecules (green), hyaluronidase genes (blue) and other putative virulence factors (red). Ring 4 shows the GC skew analysis. Ring 5 shows the G+C contents. Ring 6 and 7 show the ribosomal RNA (red) genes and transfer RNA (blue) genes identified in the genome.
