pSoxS-GFP

This composite part features the regulatory part promoter SoxS (BBa_K2610030) and the fluorescent protein GFP (BBa_E0040). It can be used to visualize upregulation of SoxS as a result of superoxide stress.

Regulatory protein SoxS is involved in the superoxide pathway in Escherichia coli. It acts a superactivator of downstream stress genes.

Usage and Biology

We, iGEM Leiden 2018, have designed this composite part as part of our project Fifty Shades of Stress. This reporter part allowed us to detect stress-induced changes in SoxS transcription.

As can be seen in figure 1, treatment with increasing concentrations of nalidixic acid leads to an increasing median fluorescence.
