RL   Submitted (FEB-2007) to the EMBL/GenBank/DDBJ databases.
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         Rule:MF_01440};
CC   -!- SIMILARITY: Belongs to the CheD family. {ECO:0000256|HAMAP-
CC       Rule:MF_01440}.
