High-torque bacterial flagellar motors assemble large periplasmic disk complexes. (AтАУC) Tomographic slices through intact cells of Salmonella (A), V. fischeri (B), and C. jejuni ┬й showing individual flagellar motors. Height of all image panels is 100 nm. (DтАУF) Slices (100 ├Ч 100 ├Ч 0.81 nm) through subtomogram averages of hundreds of motors. Color keys indicate the regions of the motor (named in GтАУI), of Salmonella (average of 286 motors) (D), V. fischeri (average of 302 motors) (E), and C. jejuni (average of 156 motors) (F). (GтАУI) Isosurface renderings of motors shown in DтАУF. FliI and FlhAC are components of the flagellar type III secretion system.: , . , , , , . , -, . , тАФ тАЬтАЭ , .

Unsymmetrized motors showing clear symmetries. C. jejuni motors (A, Left) exhibited clear 17-fold symmetry (A, Right), which was applied to improve the signal-to-noise ratio (B). V. fischeri exhibited 13-fold symmetry ┬й, which was applied to improve the signal-to-noise ratio (D)., тАЬтАЭ, . , , , Campylobacter , , , , . , .
