Protein attributes

Sequence length	364 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Involved in the modulation of the chemotaxis system; catalyzes the demethylation of specific methylglutamate residues introduced into the chemoreceptors (methyl-accepting chemotaxis proteins) by cheR By similarity.
Catalytic activity	Protein L-glutamate O(5)-methyl ester + H2O = protein L-glutamate + methanol. HAMAP MF_00099
Subcellular location	Cytoplasm. HAMAP MF_00099
Domain	The N-terminal regulatory domain inhibits the activity of the C-terminal effector domain. HAMAP MF_00099
Post-translational modification	Phosphorylated by cheA. Phosphorylation suppresses the inhibitory activity of the N-terminal domain By similarity.
Sequence similarities	Contains 1 cheB-type methylesterase domain. Contains 1 response regulatory domain.
