CC   -!- FUNCTION: Deamidates glutamine residues to glutamate on methyl-
CC       accepting chemotaxis receptors (MCPs). CheD-mediated MCP deamidation is
CC       required for productive communication of the conformational signals of
CC       the chemoreceptors to the cheA kinase.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + L-glutaminyl-[protein] = L-glutamyl-[protein] + NH4(+);

CC   -!- SUBUNIT: Forms a complex with CheC.
else
CC   -!- FUNCTION: Probably deamidates glutamine residues to glutamate on
CC       methyl-accepting chemotaxis receptors (MCPs), playing an important role
CC       in chemotaxis.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + L-glutaminyl-[protein] = L-glutamyl-[protein] + NH4(+);
