HemHp (Part:BBa_K1104202) is an OxyR-induced promoter, and was used as sensor to ROS(Reactive Oxygen Species).

HemH promoter +E0840 (Part:BBa_K1104242)

We designed the device: HemH promoter +E0840 (Part:BBa_K1104242) includes HemH promoter (Part:BBa_K1104242) and Part:BBa_E0840, induced HemH promoter by different concentrations of H2O2, and identified the strength.

In this device, after HemHp (Part:BBa_K1104202) is activated, GFP generator Part:BBa_E0840 takes as input a transcriptional signal (PoPS) and produce as output GFP (green fluorescent protein). We induced HemH promoter by different concentrations of H2O2, and measured the expression of GFP, and identified the strength.

Results

This is the relative promoter strength of BBa_K1104202 under different H202 concentrations tested using BBa_K11042042 (BBa_K1104202 +E0840) and found no significant trend where the higher the H202 concentration, the higher the promoter expression:
