The structure of the cytoplasmic domain of a serine chemotaxis receptor(TSR) of Escherichia coli is a 200 A-long coiled-coil of two antiparallel helices connected by a 'U-turn'. Two of these domains form a long, supercoiled, four-helical bundle in the cytoplasmic portion of the receptor. | The structure of the cytoplasmic domain of a serine chemotaxis receptor(TSR) of Escherichia coli is a 200 A-long coiled-coil of two antiparallel helices connected by a 'U-turn'.
