HucR-pHucO-mCherry

The “HucR-pHucO-mCherry” is composed of “Anderson Strong-RBS-HucR”(BBa_K3311003) and “pHucO-mCherry”(BBa_K3311002 ). It is a important tool for our part function test. HucR is promoted by a constitutive promoter, while the transcription of mCherry is controlled by pHucO.

Usage and Biology

As for “HucR-pHucO-mCherry” (Figure 2), while uric acid is absent, HucR will bind to pHucO operator, inhibiting the transcription of downstream genes--mCherry. In this situation, the color of the sample will not change. While uric acid is present, it will change the structure of HucR, causing it to leave pHucO, allowing mCherry to transcript, the sample will turn red. Now, we successfully constructed the plasmid “HucR-pHucO-mCherry”（Figure1-2）.
