Characterize the efficiency of promoter(BBa_K206000) with chemotaxis

BBa_K1412614: pBAD- RBS (1.0)-CheZ-TT

This part consists of [http://en.wikipedia.org/wiki/Chemotaxis CheZ] gene which can express CheZ protein make E.coli tumbling or swimming straight. In this light, we can characterize the efficiency of promoter by replacing different promoters before CheZ gene. Then we can characterize the efficiency of promoter via measuring the migration distance positively associated with the expression strength of CheZ protein.

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 pBAD promoter and before CheZ gene, ended with doiuble terminator (pBAD-RBS (1.0)-CheZ-TT). Then transfer this gene circuit into E.coli (CheZ knocked out), coat plates, and culture on semi-solid medium to measure the migration diameter of E.coli.
