Figure 2

TA skews (as in Fig. 1) for the twelve available genomes of S. pyogenes (see Table 1). Each tick mark on the vertical axes indicates 2000 T over A excess. Phagic SSRs are represented by grey rectangles while the conserved non-phagic SSR is outlined by boxed orange rectangles. In MGAS2096, MGAS6180 and MGAS10750, peculiar regions not documented as phages and presenting a different TA skew are shown with a green dotted box. These three regions are discussed in the text. Eventually, SSRs that are not described as prophages, but resemble mobile elements, are also present in the genomes of MGAS10750 and MGAS2096 and are the purpose of further studies. Phage numbering follows the order on the chromosome: in MGAS9429, 1 stands for phage 9429.1, 2 stands for phage 9429.2, etc (see references in Table 1).
