Chemotaxis phosphatase, CheZ (IPR007439)

Short name: Chemotax_Pase_CheZ

Family relationships



This family represents the bacterial chemotaxis phosphatase, CheZ. This protein forms a dimer characterised by a long four-helix bundle, composed of two helices from each monomer. CheZ dephosphorylates CheY in a reaction that is essential to maintain a continuous chemotactic response to environmental changes. It is thought that CheZ's conserved residue Gln 147 orientates a water molecule for nucleophilic attack at the CheY active site.
