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 ...

Scientists have constructed a high-resolution 3D model that shows what happens when a bacterial motor switches directions. Nagoya University scientists in Japan and colleagues at Yale University in ...

Osaka University researchers develop methods to detect pH in vivo, and elucidate phenomena driving protein export in biological activities Osaka, Japan - Bacterial cellular membranes protrude to form ...

There are billions of bacteria around us and in our bodies, most of which are harmless or even helpful. But some bacteria such as E. coli and salmonella can cause infections. The ability to swim can ...

Motor protein structure describes the structure of molecular motors capable of moving along a cytoskeletal filament. In many cases, motor proteins transport cargo in a particular direction along the ...

In a study published April 25 in Science Advances, researchers describe how components of a bacterial flagellum’s export ring are assembled. The export ring forms at the base of the flagellum and ...

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. Subscribe to our ...

Coupling of motor proteins within arrays drives muscle contraction, flagellar beating, chromosome segregation, and other biological processes. Current models of motor coupling invoke either direct ...

Most of us will probably be able to recall at least vaguely that a molecule called ATP is essential for making our bodies move, but this molecule is only a small part of a much larger system. Although ...

The ability to move is key for bacteria like some strains of salmonella and E. coli to efficiently spread infections. They can propel themselves forward using threads, known as flagella, powered by ...
