Notes

[back to top]


CheY is acetylated at lysine residues 92 and 109 by acetyl-CoA synthase (Acs). Proposed mechanism for optimum chemotaxis suggests alteration of side chain signaling state by rotation of Tyr106 side chain; this is presumably modulated by phosphorylation state of the molecule. A mutation resulting in a tyrosine to tryptophan substitution at position 106 results in a hyperactive phenotype, while a double mutation T87I/Y106W resulted in loss of activity. Substitutions at ILE95 affect FliM binding. Flagellar regulon.[2]
