pMicF
MicF small RNA, coded by the MicF gene, is produced as stress response in Escherichia coli. It negatively regulates translation of the OmpF porin. MicF binds to OmpF mRNA and represses production of OmpF in response to environmental and internal stresses. The MicF expression is stimulated by many factors such as oxidative stress, osmolarity increase and temperature increase.
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 MicFpromoter is only moderately activated by tetracycline
