CC   -!- FUNCTION: Involved in the transmission of sensory signals from the
CC       chemoreceptors to the flagellar motors. CheY seems to regulate the
CC       clockwise (CW) rotation (By similarity).
CC   -!- COFACTOR: Binds 1 magnesium ion per subunit (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasmic (Potential).
CC   -!- SIMILARITY: Contains 1 response regulatory domain.
