DegP promoter, activated by Phosporylated CpxR and SigmaE

Sequence contains 3 phosphorylated CpxR (Conjugative Plasmid eXpression) binding sites and transcription is initiated by sigma factor E (24). A native sequence has been used but it has been modified to remove Spe1 restriction site.

Function: Can detect various periplasmic stresses such as Copper (4mM CuCl2), Indole (4mM) and Ethanol (5%) (DegP is expressed by the cell to repair damage in the periplasm). We hope that it also can be used to detect presence of relevant unfolded proteins in the periplasmic space (e.g. target pharmaceuticals), to detect shear stress or other so far undefined relevant stress.
