pIbpA

Small heat shock proteins IbpA and IbpB are involved in heat shock response and oxidative stress. The promoter of IbpA has previously been defined as a possible stress probe in the heat shock response of E.coli. (Rodrigues et al, 2014)

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)

Figure 1. Heatmap with stress-activated promoters

As can be observed in Figure 1 the IbpA promoter is only moderately activated by streptomycin and tetracycline.
