Inducible ampicillin resistance cassette + RhlR expression cassette
In complex with the autoinducer molecule N-butyryl-HSL, the transcription regulator RhlR binds to specific sequences in the promoter region and enables transcription of ampR. This construct provides all the parts required to express the gene Downstream of the inducible promoter. Only RhlI, the synthase producing the autoinducer molecule N-butyryl-HSL is missing in the construct. However, N-buturyl-HSL can be taken up from the media.
Usage and Biology
The expression rate of the genes downstream of the promoter region can be tuned by the concentration of N-buturyl-HSL in the media. In this case the expression of beta lactamase can be induced by adding N-buturyl-HSL to the culture broth.
Note that due to the low level leakiness of the promoter there is background activity of the beta lactamase even when N-buturyl-HSL is not present.
