In the Escherichia coli chemotaxis system, a family of chemoreceptors in the cytoplasmic membrane binds stimulatory ligands and regulates the activity of an associated histidine kinase CheA to modulate swimming behaviour and thereby cause a net migration towards attractants and away from repellents. The chemoreceptors themselves have been shown to be predominantly dimeric, but in the presence of the kinase CheA plus an adapter protein, CheW, much higher order structures have been observed… CONTINUE READING
