Comments [?]

case <OC:Bacillus>
FUNCTIONDeamidates glutamine residues to glutamate on methyl- accepting chemotaxis receptors (MCPs). CheD-mediated MCP deamidation is required for productive communication of the conformational signals of the chemoreceptors to the cheA kinase.
CATALYTIC ACTIVITY Reaction=H2O + L-glutaminyl-[protein] = L-glutamyl-[protein] + NH4(+); Xref=Rhea:RHEA:16441, Rhea:RHEA-COMP:10207, Rhea:RHEA-COMP:10208, ChEBI:CHEBI:15377, ChEBI:CHEBI:28938, ChEBI:CHEBI:29973, ChEBI:CHEBI:30011; EC=3.5.1.44;
SUBUNITForms a complex with CheC.
else
FUNCTIONProbably deamidates glutamine residues to glutamate on methyl-accepting chemotaxis receptors (MCPs), playing an important role in chemotaxis.
CATALYTIC ACTIVITY Reaction=H2O + L-glutaminyl-[protein] = L-glutamyl-[protein] + NH4(+); Xref=Rhea:RHEA:16441, Rhea:RHEA-COMP:10207, Rhea:RHEA-COMP:10208, ChEBI:CHEBI:15377, ChEBI:CHEBI:28938, ChEBI:CHEBI:29973, ChEBI:CHEBI:30011; EC=3.5.1.44;
end case
SIMILARITYBelongs to the CheD family.
