Fig 7.

Cutaway side view of the FhaC β-barrel structure (PDB no. 2QDZ). Shown are FhaC residues that correspond to BamA residues (in parentheses) affected by the suppressor alterations. The dashed arrow points to the BamA residue A652, which is missing from FhaC. The analogous FhaC and BamA residues were taken from the ClustalW analysis carried out by Jacob-Dubuisson et al. (14). Positions of the L6 loop and the conserved VRGF/Y motif in the L6 loop are shown in beige and black colors, respectively. The image was drawn using PyMol.
