Spy, an ATP-independent chaperone, is highly upregulated in the presence of protein unfolding agent ethanol. It decreases protein degradation.
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 DH5α cells for several hours.
Figure 1. Heatmap with stress-activated promoters
As can be observed in Figure 1 the Spy promoter is activated by nalidixic acid, ethanol and chloramphenicol. This is indicative of a similar mechanism of actions for these compounds.
