Applications of BBa_K239015

Test device for BBa_K239000. Designed to detect misfolding of proteins in the periplasm or shear stress. Is activated by in stationary phase, organic chemicals like Toluene, 1-octanol, and by metals such as Copper and Iron, which can cause protein misfolding in E.coli cells.

The DegP promoter is dependent of Sigma E (and hence also the growth phase) and can not be induced only by over expression of e.g. CpxR. In comparison, the related Spy promoter (BBa_K239001), which is dependent on sigma factor 70, can be induced up to 40 fold by over expression of CpxR. (Bury-Moné et al. 2009) Experiments by the The UCL_London_2009 team have also showed that the activity of the DegP promoter, compared to the spy promoter, is much more dependent of the growth phase of the bacteria.
