Bacterial chemotaxis: a field in motion

Abstract

Many different types of studies are being combined to provide an increasingly detailed picture of the bacterial chemotaxis system. The structures of periplasmic receptors and a cytoplasmic response regulator, along with structures of domains of a membrane receptor, a receptor-modifying enzyme and a cytoplasmic histidine kinase, have been determined. These structures provide a basis for other work which is likely to open up new structural avenues.
