Protein existenceEvidence at protein level

General annotation (Comments)

Function

Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. CheY seems to regulate the clockwise (CW) rotation By similarity.

Cofactor

Binds 1 magnesium ion per subunit.

Subcellular location

Cytoplasm.

Post-translational modification

Phosphorylated by CheA By similarity.

Sequence similarities

Contains 1 response regulatory domain.
