[[ | [[https://www.uniprot.org/uniprot/CHEY_SALTY CHEY_SALTY]] Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. In its active (phosphorylated or acetylated) form, CheY exhibits enhanced binding to a switch component, FliM, at the flagellar motor which induces a change from counterclockwise to clockwise flagellar rotation. Shows autophosphatase activity which is enhanced by CheZ. [[https://www.uniprot.org/uniprot/CHEZ_SALTY CHEZ_SALTY]] Plays an important role in bacterial chemotaxis signal transduction pathway by accelerating the dephosphorylation of phosphorylated CheY (CheY-P). Acts on free CheY-P.<ref>PMID:1902474</ref> <ref>PMID:8399392</ref> <ref>PMID:8816756</ref> <ref>PMID:9837737</ref> <ref>PMID:14636076</ref> | ||
