FIG. 3.

Alignment of predicted amino acid sequences of FlaA proteins. Campylobacter strains are listed on the left. The asterisk indicates identity, whereas the colon and period indicate amino acid similarities. Boldface letters show conserved residues in Pstau and T1016 that have been shown to be glycosylated in 81-176 and VC167. Underlined letters indicate residues that may be modified given the hydrophobic nature of surrounding residues and/or conserved localization with a S/T residue that has been shown to be modified in 81-176 or VC167. Red letters indicate hydrophobic residues, whereas lilac and blue indicate residues that are negatively and positively charged, respectively. Numbers at right facilitate amino acid positioning.
