To facilitate self-assembly, the center of the flagellum is hollow, from the base all the way to the tip of the filament. The structure of the flagellum differs depending on if it is in ...

The flagellum can be divided into three parts: the basal body, the hook and the filament 4,5. The basal body is a rotary motor 6,7, and its complex structure, which is made of about 20 proteins ...

This flagellar motor consists of two main components: the rotor and the stators. The rotor is a large rotating structure, anchored to the cell membrane, that turns the flagellum. On the other hand, ...

EpsE is thought to "sit down," as Kearns describes it, on the flagellum's rotor, a donut-shaped structure at the base of the flagellum. EpsE's interaction with a rotor protein called FliG causes a ...

When speaking of motors, most people think of those powering vehicles and human machinery. However, biological motors have existed for millions of years in microorganisms. Among these, many ...

This video presents a study in which, using cryo-electron microscopy, researchers determined the structure and mechanisms of a key component in the flagellar motor, which bacteria use to turn ...

Pili are shorter and thinner than flagella. While flagella are rigid, with torque generated by the motor, pili are less rigid and straighter. Pili can be found evenly around the surface of the ...
