FIG. 2.

Phylogenetic tree of L. brevis PtsK with several of its homologues from other bacteria. The phylogenetic tree was derived using the ClustalX program. Bootstrapping was applied, and bootstrap values (the relative probabilities for occurrence of internal nodes for the tree), based on 1,000 random runs, are provided. Abbreviations: Lbr, Lactobacillus brevis; Efa, Enterococcus faecalis; Sbo, Streptococcus bovis; Smu, Streptococcus mutans; Ssa, Streptococcus salivarius; Bsu, Bacillus subtilis; Sxy, Staphylococcus xylosus; Tpa, Treponema pallidum; Mge, Mycoplasma genitalium; Mpn, Mycoplasma pneumoniae. A very similar tree was generated with the TREE program (data not shown).
