RT "A phylogenomic and molecular marker based taxonomic framework for the
RT order Xanthomonadales: proposal to transfer the families Algiphilaceae and
RT Solimonadaceae to the order Nevskiales ord. nov. and to create a new family

RT containing the genus Rhodanobacter and its closest relatives.";

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 -!- 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 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}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
