Flagella are primarily used for cell movement and are found in prokaryotes as well as some eukaryotes. The prokaryotic flagellum spins, creating forward movement by a corkscrew shaped filament. A ...

The flagellum is one of nature's smallest and most powerful motors. The flagellum of some bacteria can, for example, rotate more than 200 times per second, driven by 1,400 piconewton-nanometers of ...

Archaea use flagella known as archaella—distinct both in protein composition and structure from bacterial flagella—to drive cell motility, but the structural basis of this function is unknown ...

Actually, flagella vary widely from one species to another, and some of the components can perform useful functions by themselves. They are anything but irreducibly complex It is a highly complex ...

In Microcosm, I tell the story of how E. coli was embraced by the creationists. In particular, they adore the flagellum, the fast-spinning tail that E. coli and many other bacteria use to zip around.

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 ...
