Characterize efficiency of RBS with chemotaxis

BBa_K1412829: Plac-RBS(0.3)-cheZ-TT

This part consists of [http://en.wikipedia.org/wiki/Chemotaxis cheZ] gene which can express CheZ protein makes E. coli tumble or swim straight. In this light, we can characterize the RBS efficiency by just change different RBS. Then we can characterize the efficiency of RBS via measuring the migration distance positively associated with the expression strength of CheZ.


Figure 1.The schematic diagram of how we characterize the activity of promoters.


Usage

When we want to characterize the efficiency of RBS, we usually connect the RBS with GFP, and then measure the fluorescence intensity of GFP. In our part, you only need to connect RBS after a Plac promoter and before cheZ gene, ending with a double terminator(Plac-RBS(changeable)-cheZ-TT). Then transferred this gene circuit into E. coli CL-1 (cheZ knocked out), and coated plates, cultured on semi-solid medium to measure the migration diameter of E. coli.
