CC -!- FUNCTION: Probably deamidates glutamine residues to glutamate on
CC methyl-accepting chemotaxis receptors (MCPs), playing an important role
CC in chemotaxis. {ECO:0000256|HAMAP-Rule:MF_01440}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-glutaminyl-[protein] + H2O = 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_01440};
CC -!- SIMILARITY: Belongs to the CheD family. {ECO:0000256|HAMAP-
CC Rule:MF_01440}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
