pDawn - Endolysin/Holin
The plasmids pDawn for light-activated gene expression. Basically, the YF1/FixJ drives gene expression from the pFixK2 promoter in a blue-light repressed manner. When we insert the λ phage repressor cI and the λ promoter pR in pDawn, this will invert the signal polarity and lead to the gene expression.
The histidine kinase YF1 employs a light oxygen voltage blue light photosensor domain. In the absence of blue light, YF1 phosphorylate the regulator FixJ which induces gene expression from the FixK2 promoter. The opposite happens with pDawn.
Toxins will be produced after light stimulation and induce lysis.

Design Notes
We obtained the plasmids from the Centre for Biological Signalling Studies and the University of Freiburg. As soon as we received them, we observed that the multiple cloning site as well as the λ promoter pR were located upstream the YF1/FixY system.
