xylR+PxylA+RBS+ydcE+Ptms+RBS+ydcD: Cell Growth Inhibition Device
iGEM Registry Part: BBa_k733012
This part is a growth inhibition device that makes a cell release BMP2 which slows or stops the growth of bacteria. In the future, this part can be modified to keep the cell population of our E. coli controlled in the colon of humans or in water. It would prevent the cells from growing and overtaking the cells already living in the ecosystem. This part is already modified for cells in the colon and could be a great addition to our E. coli.
Phytochelatin (PC) EC20 fused to linker-dCBD with LacI
iGEM Registry Part: Part:BBa_K1321110
This part uses the double cellulose binding domain (dCBD) that is part of the packaging for our E. coli. This dCBD linker creates a site within the dCBD that binds the cellulose to a metal. This can be useful for our project if we combine it with our dCDB, because it could recognize the presence of a metal with the potential to harm humans when the E. coli cells are in the digestive system or water sample. With this additional part, the cellulose would bind to the metal and trap it so that it can then be tested for different metals.
