Hyper-variable regions containing multiple diverse PTS transporters. Genes are shown with bars along the sequences, where PTS transporters are shown in colour, and all other genes are shown in white. Red = Glc family, blue = Man family, purple = Gat family, green = Fru family, orange = Lac family, pink = Asc family (family designation according to ). Numbers above Man family transporters indicate their annotations as shown in Figure 8. The strain phylogeny is as in Figure 1, and similarity between the sequences is shown with connecting grey lines as estimated using tblastx with no filtering.
