Design of a AlcR/acetaldeyhde repressed promotor PAlcR

For the promotor PAlcR the operator site of AlcR-inducer from apergillus nidulans was placed between the -10 and -35 region of the strong promotor. While acetaldeyhde is bind to AlcR, the complex will bind to the operon and block the binding of the RNA-polymerase.

Design of the promotor for the AlcR-system, the operon sequence is designed between the -10 and the -35 region (blue) of a strong promotor with inverted and direct-repeats.


Design of the test-system

To test our designed AlcR-promotors the following system was designed (see Figure). To induce the expression of AlcR a tetracycline induced promotor was used. To monitor the expression of AlcR a His-tag was introduced. In present of acetaldeyhde AlcR binds to the AlcR operon and inhibits the expression of GFP. For a better signal assam gfp was used.

Design of our testsystem.
