Protein attributes

Sequence length	364 AA.
Sequence status	Complete.
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. HAMAP MF_00099
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. HAMAP MF_00099
Sequence similarities	Contains 1 cheB-type methylesterase domain. Contains 1 response regulatory domain.
