Signaling and sensory adaptation in Escherichia coli chemoreceptors: 2015 update

Highlights • Escherichia coli uses transmembrane chemoreceptors to detect environmental chemicals. • Chemoreceptors convey signals through dynamic shifts in coupled structural elements. • Core signaling complexes contain six receptors coupled to one kinase molecule. • Networked core complexes form c...

Description
Summary:Highlights • Escherichia coli uses transmembrane chemoreceptors to detect environmental chemicals. • Chemoreceptors convey signals through dynamic shifts in coupled structural elements. • Core signaling complexes contain six receptors coupled to one kinase molecule. • Networked core complexes form cooperative, high-amplification signaling arrays.
