CC   -!- FUNCTION: Involved in chemotaxis. Part of a chemotaxis signal
CC       transduction system that modulates chemotaxis in response to various
CC       stimuli. Catalyzes the demethylation of specific methylglutamate
CC       residues introduced into the chemoreceptors (methyl-accepting
CC       chemotaxis proteins or MCP) by CheR. Also mediates the irreversible
CC       deamidation of specific glutamine residues to glutamic acid.
CC       {ECO:0000255|HAMAP-Rule:MF_00099}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[protein]-L-glutamate 5-O-methyl ester + H2O = H(+) + L-
CC         glutamyl-[protein] + methanol; Xref=Rhea:RHEA:23236, Rhea:RHEA-

CC         Rule:MF_00099};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + L-glutaminyl-[protein] = L-glutamyl-[protein] + NH4(+);
CC         Xref=Rhea:RHEA:16441, Rhea:RHEA-COMP:10207, Rhea:RHEA-COMP:10208,

CC         Rule:MF_00099};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00099}.
CC   -!- DOMAIN: Contains a C-terminal catalytic domain, and an N-terminal
CC       region which modulates catalytic activity. {ECO:0000255|HAMAP-
CC       Rule:MF_00099}.
CC   -!- PTM: Phosphorylated by CheA. Phosphorylation of the N-terminal
CC       regulatory domain activates the methylesterase activity.
CC       {ECO:0000255|HAMAP-Rule:MF_00099}.
CC   -!- SIMILARITY: Belongs to the CheB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00099}.
