Characterize the efficiency of pTetR (R0040) with chemotaxis


BBa_K1412014: pTetR-RBS(1.0)-CheZ-TT

This part is consist of [http://en.wikipedia.org/wiki/Chemotaxis CheZ] gene which can express CheZ protein make E.coli tumble or swim straight. In this light, we can characterize the efficiency of promoter by replacing 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 connect the promoter with GFP, then measuring the fluorescence intensity of GFP. In our part, you just need connect RBS(1.0) after a pTetR promoter and before CheZ gene, ending with double 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.
