FIG. 1.

Circular representation of the S. pyogenes strain NZ131 genome. Outer circle shows COG functional categories of coding regions in the clockwise direction. The lines in each concentric circle indicate the position of the represented feature; the color key is show to the right of the map. The second circle shows predicted coding regions transcribed on the forward (clockwise) DNA strand. The third circle shows predicted coding regions transcribed on the reverse (counterclockwise) DNA strand. The fourth circle shows COG functional categories of coding regions in the counterclockwise direction. The fifth circle shows mobile genetic elements and bacteriophage genomes (red). The sixth circle shows rRNA operons (dark gray). The seventh and eighth circles show the percent G+C content of the sequence and the percent G+C deviation by strand, respectively.
