The flagellar motor switch in Escherichia coli and Salmonella typhimurium regulates the direction of flagellar rotation and hence controls swimming behaviour. The switch is a complex apparatus that responds to signals transduced by the chemotaxis sensory signalling system during chemotactic behaviour [PMID: 8224881]. The switch complex comprises at least three proteins - FliG, FliM and FliN. It has been shown that FliG interacts with FliM, FliM interacts with itself, and FliM interacts with FliN [PMID: 8631704]. The proteins are not particularly hydrophobic and may be peripheral to the membrane, possibly mounted on the basal body M ring [PMID: 2656645, PMID: 1631122].
This entry represents the flagellar motor switch proteins:FliN and FliY, and the related type III secretion protein hrcQb.
