We analysed L. mexicana flagellum length, structure and biochemical changes, using electron microscopy and cell lines-expressing enhanced green fluorescent protein (eGFP) fusions of axonemal proteins, ...

The bacterial flagellum is a complex organelle that is required for the motility that is driven by an ion-powered rotary motor. The assembly of multiple flagellar organelles in a single cell is ...

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 ...

BLOOMINGTON, Ind. -- A tiny but powerful engine that propels the bacterium Bacillus subtilis through liquids is disengaged from the corkscrew-like flagellum by a protein clutch, Indiana University ...

Researchers used biochemical techniques and electron microscopy to uncover the structure of the bacterial MotA protein, which forms part of the propeller motor (flagellum). Three-dimensional analysis ...

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 their ...

Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology’s most intensively studied molecular machines. Bacteria move through ...

(Nanowerk News) 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, ...

Most bacteria have flagella; they are threadlike appendages extending from the surface of many microbes. They help move the organism around, a function called motility, in a rotating motion. Enabling ...

Scientists have studied a new target for antibiotics in the greatest detail yet – in the fight against antibiotic resistance. The ‘molecular machine’ flagellum is essential for bacteria to cause ...
