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:0000256|HAMAP-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 ChEBI:CHEBI:15377, ChEBI:CHEBI:28938, ChEBI:CHEBI:29973,
CC ChEBI:CHEBI:30011; EC=3.5.1.44; Evidence={ECO:0000256|HAMAP-
CC 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 COMP:10208, Rhea:RHEA-COMP:10311, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17790, ChEBI:CHEBI:29973,
CC ChEBI:CHEBI:82795; EC=3.1.1.61;
CC Evidence={ECO:0000256|ARBA:ARBA00000941, ECO:0000256|HAMAP-
CC Rule:MF_00099};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00099}.
CC -!- DOMAIN: Contains a C-terminal catalytic domain, and an N-terminal
CC region which modulates catalytic activity. {ECO:0000256|HAMAP-
CC Rule:MF_00099}.
CC -!- PTM: Phosphorylated by CheA. Phosphorylation of the N-terminal
CC regulatory domain activates the methylesterase activity.
CC {ECO:0000256|HAMAP-Rule:MF_00099}.
CC -!- SIMILARITY: Belongs to the CheB family. {ECO:0000256|HAMAP-
CC Rule:MF_00099}.
