CheZ is responsible for the dephosphorylation of flagellum-regulating protein CheY. It has been reported that cheZ-/- strain has a higher frequency of direction change and thus a narrower range of mobility. This device rescues cheZ-/- cells in the presence of IPTG.
Notes
None.

cheZ CDS is cloned from Escherichia coli JM109 strain. Other sequences are from BioBrick parts.
