Conclusion
Recent high-resolution structural analyses have provided insights into the assembly, rotation, and directional switching mechanisms of the bacterial flagellar motor complex.
Supporting Evidence
- Bacteria swim by rotating flagella, which are complex structures made of many proteins.
- The flagellar motor consists of a rotor and stator units that convert ion flow into mechanical work.
- Recent cryo-electron microscopy studies have revealed detailed structures of the flagellar motor components.
Takeaway
Bacteria use a tiny motor to spin their tails, helping them swim and move toward food or away from danger. Scientists have learned a lot about how this motor works and how it changes direction.
Methodology
This review summarizes recent findings from high-resolution cryo-electron microscopy studies of the bacterial flagellar motor.
