Chemoreceptors are crucial components in the bacterial sensory systems that mediate
chemotaxis. Chemotactic responses exhibit exquisite sensitivity, extensive dynamic range …

Bacterial chemoreceptors mediate chemotaxis by recognizing specific chemicals and
regulating a noncovalently associated histidine kinase. Ligand binding to the external …

Motile bacteria respond to environmental cues to move to more favorable locations. The
components of the chemotaxis signal transduction systems that mediate these responses …

Chemotaxis is a mechanism by which bacteria efficiently and rapidly respond to changes in
the chemical composition of their environment, approaching chemically favorable …

The chemotactic sensory system of Escherichia coli comprises membrane-embedded
chemoreceptors and six soluble chemotaxis (Che) proteins. These components form …

Bacterial chemoreceptors are transmembrane homodimers that can form trimers, higher
order arrays, and extended clusters as part of signaling complexes. Interactions of dimers in …

Spatial organization of signalling is not an exclusive property of eukaryotic cells. Despite the
fact that bacterial signalling pathways are generally simpler than those in eukaryotes, there …

Coliform bacteria detect chemical attractants by means of a membrane-associated cluster of
receptors and signalling molecules. We have used recently determined molecular …

The chemotaxis network in Escherichia coli is remarkable for its sensitivity to small relative
changes in the concentrations of multiple chemical signals over a broad range of ambient …

Motile bacteria seek optimal living habitats by following gradients of attractant and repellent
chemicals in their environment. The signaling machinery for these chemotactic behaviors …
