Protein name

RecName: Full=Probable chemoreceptor glutamine deamidase CheD; EC=3.5.1.44;

Gene name

cheD

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 (By similarity).

CATALYTIC ACTIVITY: Protein L-glutamine + H(2)O = protein L-glutamate + NH(3).

SUBUNIT: Forms a complex with CheC (By similarity).

FUNCTION: Probably deamidates glutamine residues to glutamate on methyl-accepting chemotaxis receptors (MCPs), playing an important role in chemotaxis (By similarity).

CATALYTIC ACTIVITY: Protein L-glutamine + H(2)O = protein L-glutamate + NH(3).

SIMILARITY: Belongs to the CheD family.
