Extended Data Fig. 1: Multiple sequence alignment of flagellins FlaA-D.
From: Structures of the sheathed flagellum reveal mechanisms of assembly and rotation in Vibrio cholerae

Note that residues (259-267) are highlighted in blue. Residues (268-274, red) in FlaA exhibit a distinct morphology compared to other flagellins (FlaB, FlaC, and FlaD) due to two extra residues (K275 and T276, magenta).
