pRpoE
The gene rpoE encodes the sigma factor E, a protein in Escherichia coli and other species of bacteria. RpoE appears to be necessary for the exocytoplasmic stress response. E. coli mutants without rpoE are not able to grow at temperatures above 42 degrees Celsius.
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.

As can be observed in Figure 1 the RpoE promoter is activated by, amongst others, chloramphenicol, ethanol and nalidixic acid.
