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, ...

Prokaryotic cells have evolved numerous machineries to swim through liquid or crawl over surfaces. Perhaps the most common of these are the well-studied bacterial flagella and the unrelated archaeal ...

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 ...

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 ...

The axoneme of a mature flagellum in a sperm of Polytrichum juniperinum contains a double helix of two 500 Å ribbons, between the central fibers and the peripheral doublets. This double helix ...

They are the tiny motors present in many of the human body's most complex systems. Cilia are hair-like structures that oscillate in waves, and are present in the brain, kidneys, lungs and reproductive ...

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 ...

A new type of enzyme has been discovered in hundreds of bacterial species, and researchers say it helps reveal how bacteria invade organisms. Reporting in Nature Communications, this work may help us ...

It has been long been known that bacteria swim by rotating their tail-like structure called the flagellum. (See the swimming bacteria in the figure.) The rotating motion of the flagellum is powered by ...
