The CFY is a bacteriocin in the colicin family. It is produced naturally by Y.frederiksenii and target close relatives to that bacteria. One among them is the Y.enterocolitica, which is our target pathogen. The colicin Fy will target the cell membrane of its target.
PelB is en export tag that works in E.coli.
The killing system
We designed the killing system to secret the colicin Fy with the help of an export tag, pelB. The part contains the colicin Fy BBa_K1381017, the export tag for E.coli, pelB, and a RBS. This part do not have any promoter. It is desgined that way so it can be easier to couple a promoter of your choice with the rest of the killing system. We used the regular Biobrick standard 10 to couple them, which results in a stop codon between pelB and CFY. For this part to work, the stop codon must be removed with mutagenesis. This part also contains an 6x His-tag for characterisation.
