CC   -!- FUNCTION: Probably deamidates glutamine residues to glutamate on
CC       methyl-accepting chemotaxis receptors (MCPs), playing an important role
CC       in chemotaxis. {ECO:0000255|HAMAP-Rule:MF_01440}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + L-glutaminyl-[protein] = L-glutamyl-[protein] + NH4(+);
