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 ...

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 ...

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 ...

When headed the wrong way, some bacteria turn by letting their propellers flop. The newly discovered turning mechanism explains how a marine bacterium can control its direction using only a single ...

THREE years before his death in 1805, English philosopher William Paley proposed a now-famous thought experiment. Imagine discovering a watch on the heath: how would you explain its intricate ...

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 ...
