Design Notes

T. maritima encapsulin surface display and cargo loading were previously shown in BioBricks BBa_K3111501 and BBa_K3111402. In these experiments we looked at how we can use these properties for the construction of a drug delivery platform.

To induce cytotoxic action, we proceeded with loading of the encapsulin system with a fluorescent photosensitiser protein, miniSOG (BBa_K3111032). Under blue-light illumination, miniSOG is activated and generates reactive oxygen species which are damaging to cells (1). To achieve this we cloned BBa_K3111501 and BBa_K3111302 together to construct the plasmid observed in Figure 1.
