pDawn promoter system can be activated by blue light. blrA can be activated by blue light and produce reactive oxygen species(ROS).
Biology and Usage
pDawn is a kind of regulation system that has been illustrated effectively in Vibrio natriegens which based on optogenetics. Under the irradiation of blue light, a series of regulatory elements will work on regulating the expression of genes that inserted into multiple cloning site In its downstream.
BlrA, originating from Bacillus subtilis, is a blue light-induced GTP-binding receptor, which possesses the LOV domain and autofluorescence. LOV domain enables it to be activated by blue light and produce ROS, which can damage the bacterial structure.
We take blrA as the core of our kill switch, combine it with inducible promotor system, terminator and a series of necessary elements. The whole part is inserted into a plasmid backbone and finally transformed into E.coli to gain enough correct and functional circuits. The circuits are transformed into Vibrio.natriegens. We choose growth curve and CFU to measure the killing effect of BlrA.
