The bacterial flagellum is a helical filamentous organelle responsible for motility. In bacterial
species possessing flagella at the cell exterior, the long helical flagellar filament acts as a …

Motile Escherichia coli cells track gradients of attractant and repellent chemicals in their
environment with transmembrane chemoreceptor proteins. These receptors operate in …

Chemotaxis allows bacteria to follow gradients of nutrients and other environmental stimuli.
The bacterium Escherichia coli performs chemotaxis via a run-and-tumble strategy in which …

For organisms to coordinate their growth and development with nutrient availability, they
must be able to sense nutrient levels in their environment. Here, we review select nutrient …

Physical Biology of the Cell is a textbook for a first course in physical biology or biophysics
for undergraduate or graduate students. It maps the huge and complex landscape of cell …

Bacteria use chemotaxis to migrate towards environments that are better for growth.
Chemoreceptors detect changes in attractant levels and signal through two-component …

The recent rapid accumulation of knowledge on the dynamics and structure of the plasma
membrane has prompted major modifications of the textbook fluid-mosaic model. However …

Pseudomonads sense changes in the concentration of chemicals in their environment and
exhibit a behavioral response mediated by flagella or pili coupled with a chemosensory …

Chemotaxis is the directed motility by means of which microbes sense chemical cues and
relocate towards more favorable environments. Methyl-accepting chemotaxis proteins …

The bacterial flagellum is one of nature's most amazing and well‐studied nanomachines. Its
cell‐wall‐anchored motor uses chemical energy to rotate a microns‐long filament and …
