Disease relevance of cheA

  • 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].

Psychiatry related information on cheA

  • The unusual behaviour of the cheA mutant and the identification of two homologues of cheY suggests that R. sphaeroides has at least two pathways controlling motor activity [2].
