FIG 8.

Phylogenetic analysis of flagellin paralogs in C. crescentus. (A) Sequence alignment of the six flagellins present in C. crescentus. The observed secondary structure in FljK is annotated above the sequence alignment. Conserved surface-exposed threonine residues that harbor posttranslational modifications are highlighted yellow. Note that the most divergent flagellin, FljJ, lacks most of such threonine residues. (B) Conservation mapping of C. crescentus flagellins with the program ConSurf (65). The greatest degree of sequence divergence is located along the surface of the flagellin.
