blrA

blrA can be activated by blue light and produce reactive oxygen species(ROS).


Biology

Flavin-combined fluorescent protein, coded by a kind of optogenetic toolbox LOV(light-oxygen voltage)-based photosensitizer gene, can induce the light-driven killing of bacteria. 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.

Usage

We take blrA as the core of our kill switch, combine it with promotor, 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.
