Figure 5. Schematic illustration of flagella motor. The basic elements of the flagella rotary motor are shown. The basal body is formed by the membrane integral M/S-ring and its cytoplasmic extension, the C-ring, and connects via a curved hook to the flagellum. These parts are thought to comprise the rotary part of the flagella motor. The membrane-spanning Mot complexes build the stator that allows for torque generation. For more detailed information on architecture and function, see Macnab (1996, 1999).
