RBS (0.01) CheZ double terminators -- derivative of BBa_K1412005

This part is a derivative of BBa_K1412005 . It consists of a cheZ coding region and a RBS coding region whose relative efficiency is 0.3. This part does not pose any biological threat. With a promoter of your interest, this device rescues the mobility of cheZ-/- cells. It has been reported that cheZ-/- strain has a higher frequency of direction change and thus a narrower range of mobility.


Usage

1.We performed a swarming assay to characterize the motility of CheZ-deficient strain CL1 and cells transformed with CheZ-expressing plasmid BBa_K1412001 .

Our results clearly show that CheZ-deficient mutants show smaller diffusion, while they are rescued by our BBa_K1412001 plasmid.


2.We also performed a swarming assay to characterize characterize the strength of RBS with CL1 cells. Three strains of CL1 are transformed with CheZ-expressing plasmid of different RBS efficiency (BBa_B0034 :1.0 ; BBa_B0032 :0.3 ; BBa_B0033 :0.01 ).

Changing different RBS in the same circuit, we can characterize the efficiency of RBS, since the expression strength of CheZ is positively associated with the efficiency of RBS.
