Design Note

We made full use of the two-component system found in Salmonella. We try to change the Iron binding motif to 12 lathanide binding tags in the membrane protein PmrB. Then PmrB can activate PmrA by phosphorylating it. Phosphorylated PmrA is going to activate promoter PmrC and GFP can be expressed. In the end, the sensing system can detect the concentration of lanthanide nearby.


Resources

Our LBT.PmrA-PmrB(Fe).PmrC-GFP were synthesized by IDT. Then we used SOE (splicing by over-lapping extension) to change the Iron binding motif to 12 lathanide binding tags in the membrane protein PmrB. Moreover, we use restriction enzyme and ligase to fuse the PmrA-PmrB(LBT) and PmrC-GFP. </h1>References</h1>
