MiniNano for bacterial surface display
This construction consists of 4 described parts. These are: Codon optimalised INPNC for Surface Display (BBa_K4375007), flexible GS-linker (BBa_K4375010), miRFP670 nano (BBa_K4375008), J23101* (BBa_K4375003). They allow the bacterium to be expelled to the tumor surface, thus allowing its visualisation and colonisation on the tumour surface.
Usage and Biology
The MiniNano is a compact construct meant for extracellular protein (like tumor-specific receptor, antigen, etc.) detection via fluorescence. This protein has 3 domains. (1) INPNC surface display module (INPNC codes for N- and C- terminal domain of Ice Nucleation Protein (INP) from Pseudomonas syringe, and it is used for displaying proteins on bacteria's outer membrane (BBa_K4375007). It is linked to (by a flexible GS-linker, BBa_K4375010) (2) a small, near-infrared emitting fluorescent protein, miRFP670 nano (BBa_K4375008), which is connected to an anti-EGFR specific Nanobody, 7D12, via llama-derived IgA hinge region linker (BBa_K4375011). Moreover, it contains a Myc epitope tag, so the specific interaction can be detected with labelled antibodies. This complex detection device is expressed under the constitutive promoter J23101* (BBa_K4375003) The Nanobody in the construct can be easily swapped with other protein domains, as its sequence is framed by BamHI and SphI restriction sites
