Figure 1

Flagellar and chemotaxis proteins and their putative locations and interactions. The protein components of the major elements of the flagellum, the external filament, the hook, the basal body, and the motor-switch complex are shown. The external flagellar proteins that form the rod, hook, and filament are secreted by a specific export apparatus forming at the cytoplasmic side of the MS ring. The proton gradient at the cytoplasmic membrane drives a proton flow that energizes flagellar motor rotation. The direction of rotation is determined by the interaction of FliM in the motor-switch complex with the chemotaxis regulator CheY, whose activity is regulated by the other components of the chemotaxis system. Symbols: H+, protons; P, phosphate; CH3, methyl group.
