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

The bacterial flagellum is an amazingly complex molecular machine with a diversity of roles
in pathogenesis including reaching the optimal host site, colonization or invasion …

Clustering of proteins into micrometer-sized structures at membranes is observed in many
signaling pathways. Most models of clustering are specific to particular systems, and …

Electron microscopy played a key role in establishing cell biology as a discipline, by
producing fundamental insights into cellular organization and ultrastructure. Many seminal …

Bacterial chemotaxis is a biased movement of bacteria toward the beneficial chemical
gradient or away from a toxic chemical gradient. This movement is achieved by sensing a …

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

Cryo-electron tomography provides low-resolution 3D views of cells, organelles, or viruses.
