Design Notes

In order to quickly test the effect of our amplifier, we used T7 promoter with strong transcriptional activity.


Source

The natural gene regulatory architecture in the hrp control network contains the ingredients of a tunable transcriptional amplifier: The activator proteins HrpR and HrpS form a ultrasensitive high-order co-complex, which bind the upstream activator sequence of the hrpL promoter to remodel the closed σ54 -RNAP-hrpL transcription complex to an open one through ATP hydrolysis.[2]
