RBS (0.01) CheZ double terminators -- derivative of BBa_K1412005
This part is a derivative of BBa_K1412005 but weaker than it. It consists of a CheZ coding region and a RBS coding region whose relative efficiency is 0.01. 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 CL-1 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 the strength of RBS with CL-1 cells. Three strains of CL-1 are transformed with CheZ-expressing plasmid of different RBS efficiency (BBa_B0034 :1.0 ; BBa_B0032 :0.01; 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.
