Figure 2. Structural models of β-barrel outer membrane proteins in Group A. Group A consists of 13 proteins. (A-C) Proteins with 16 b-strands;
(F-H) predicted trimeric structures of TolC family proteins. The remaining proteins exhibit eight-stranded β-barrel structures (D-E, I-M). β-strands,
α-helices, and loops are colored yellow, blue, and magenta, respectively. Green spheres indicate amino acid variations identified across nine strains of
Brachyspira pilosicoli. Proteins with more than 40 variations are shown in green ribbon representation.
