Disease relevance of cheZ

  • The 3D trajectories were generated for wild-type Escherichia coli strain RP437 as well as for isogenic derivatives that display smooth swimming due to a cheA deletion (strain RP9535) or incessant tumbling behavior due to a cheZ deletion (strain RP1616) [1].

High impact information on cheZ

  • The behavioral defect produced by overproduction of the CheW protein does not require the presence of the cheR, cheB, or cheZ gene [2].
