pCpxR
The CpxR protein is a member of the two-component regulatory system CpxA/CpxR which responds to envelope stress response by activating expression of downstream genes.(Batchelor et al, 2005)

Usage and Biology
iGEM Leiden 2018 has created a screening system for the detection of new antibiotics. We have tested several stress-activated promoters against a repertoire of known antibiotics (Figure 1) using flow cytometry. We fused promoters to green fluorescent protein and stressed transformed DH5a cells for several hours.
Figure 1. Heatmap with stress-activated promoters
As can be observed in Figure 1 the CpxR promoter is only moderately activated by hydrogen peroxide.
