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

Required for aerobic and anaerobic chemotaxis. 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.
