case <OC:Bacillus> | |
FUNCTION | Deamidates 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; |
SUBUNIT | Forms a complex with CheC. |

FUNCTION | Probably 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 | |
SIMILARITY | Belongs to the CheD family. |
