Identification of traAB orthologs across the order Myxococcales. (A) The monophyletic order Myxococcales currently contains three well-defined suborders, 10 families, and 31 genera. Genera that harbor or lack traAB orthologs are indicated, whereas genera with unavailable genomic sequences are shaded in gray. *, family affiliation not designated. (B) Schematics of multiple-sequence alignments of 78 TraA/B orthologs across the order Myxococcales. Amino acid residues are displayed using the Clustal X default scheme. The traAB operon is shown at the top. Domain architectures of TraA/B are labeled as follows: SS, type I signal sequence; CA, Cys-A region; Mx-CT, MYXO-CTERM (TIGR03901); TSP-3, thrombospondin type 3 (Pfam02412); CTD, carboxyl-terminal domain. Suborders of the aligned TraA/B sequences are indicated on the left.
