Phylogenetic analysis of the SPOA domain-containing family of flagellar proteins. (A) Unrooted phylogenetic tree of aligned sequences of FliM, FliN, and FliY from 12 bacteria from the spirochetes, Firmicutes, Epsilonproteobacteria, and Gammaproteobacteria. Confidence values were generated through 1,000 bootstrap repeats. Branches are shaded red for FliM, green for FliY, and blue for FliN. (B) Genomic organization and conserved encoded domains of fliM, fliN, and fliY. The SPOA domain (Pfam domain pf01052) is shown in black, and the presence of true (yellow) and potential degenerate (gray) EIDAL motifs is indicated. Adjacent genes indicate adjacent genomic locations, whereas slashes indicate distant locations.
