A tiny but powerful engine that propels the bacterium Bacillus subtilis through liquids is disengaged from the corkscrew-like flagellum by a protein clutch, scientists have learned. Scientists have ...

The bacterial flagellum. (A) Electron micrograph of a Salmonella cell. (B) Electron micrograph of the Salmonella flagellum. (C) Schematic diagram of the flagellum. The flagellum consists of at least ...

Many species of swimming bacteria have a rotary structure called a "flagellum," consisting of more than twenty different kinds of proteins. By rotating their flagellar filaments and gaining propulsion ...

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, ...
