Characterize the efficiency of pTetR (R0040) with chemotaxis
BBa_K1412014: pTetR-RBS(1.0)-CheZ-TT
This part consists of a [http://en.wikipedia.org/wiki/Chemotaxis CheZ] gene which can express CheZ protein deciding E.coli whether tumble or swim straight. In this light, we can characterize the efficiency of promoter by just change different promoters. Then we can characterize the efficiency of promoter via measuring the migration distance positively associated with the expression strength of CheZ.
Usage
When we want to characterize the efficiency of promoter, we usually link the promoter with GFP, then characterize the promoter by just measure the fluorescence intensity of GFP. In our part, you need just link RBS(1.0) after a pTetR promoter and before a CheZ gene, ending with a TT terminator(pTetR-RBS(1.0)-CheZ-TT). Then transfer this gene circuit into E.coli (CheZ knocked out), and coat plates, culuture on semi-solid medium to measure the migration diameter of E.coli.

Protocol
Genetic link stage
1.As a skeleton, TT terminator link with CheZ.
2.Then the skeleton CheZ-TT link to RBS(1.0).
3.Next, link RBS(1.0)-CheZ-TT with promoter pTetR.
Characterization stage
1.Transfer the part pTetR-RBS(1.0)-CheZ-TT into E.coli (CheZ knock out), and coat plates, culture for hours to measure the migration diameter of E.coli.
