Chemotaxis protein CheY

Gene

cheY

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. Phosphorylated CheY interacts with the flagella switch components FliM and FliY, which causes counterclockwise rotation of the flagella, resulting in smooth swimming.2 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
