Sequence alignment of the seven flagellin subunits of R. leguminosarum bv. viciae strain 3841. Asterisks represent conserved residues; colons represent conserved substitutions; dots represent semi-conserved substitutions. The tryptic peptides detected in the upper band for 3841wt flagellar preparations are highlighted. FlaA peptides are highlighted in yellow; FlaB peptides are highlighted in gray; FlaC peptides are highlighted in teal. The peptides unique for the flagellin subunit are underlined. The glycosylation signals are in boxes. The sequence coverage of FlaA, FlaB, and FlaC are 44%, 37%, and 31%, respectively.
