FIG 4.

Bioinformatic analyses of TraA orthologs from the suborder Cystobacterineae. (A) Maximum likelihood tree showing the relationships among diverse Cystobacterineae TraA orthologs (full length). Families and genera are indicated by outlines and colors, respectively. Each allele prefix indicates its taxonomic origin (see Table 1 for details). TraA orthologs that were functionally characterized are marked with black dots. The scale bar represents the number of amino acid substitutions per residue. Bootstrap values (%) are color coded. (B) Heat maps showing sequence conservation of TraA orthologs from the suborder Cystobacterineae and the genus Myxococcus. TraA domain organization is indicated.
