Structural differences in the bacterial flagellar motor among bacterial species

摘要: The bacterial flagellum is a supramolecular motility machine consisting of the basal body as rotary motor, hook universal joint, and filament helical propeller. Intact structures flagella have been observed for different species by electron cryotomography subtomogram averaging. core C ring, MS rod protein export apparatus, their organization are well conserved, but novel divergent also visualized to surround conserved structure body. This suggests that flagellar motors adapted function in various environments where bacteria live survive. In this review, we will summarize our current findings on motor.
