T7p(BBa_I719005)+RBS(B0034)+Lpp-OmpA+MBP(surface display of mercury binding peptide)
This part is the combination of a T7promoter(BBa_I719005),RBS(B0034)and Lpp-OmpA+MBP(surface display of mercury binding peptide).It functions as the surface display part of MBP in our project.
Description
It is highly expected that when fused with N-terminal fragment of Outer membrane protein A (OmpA), the mercury metal binding peptide(MBP)will be translocated and displayed on the surface of bacteria, which will contribute a lot to increase the mental binding capacity when combined will other collection parts.
Lpp-OmpA-mbp is designed as a fusion protein consisting of the signal sequence and first 9 amino acid of Lpp, residue 46~159 of OmpA and the metal binding peptide(MBP). The signal peptide of the N-termini of this fusion protein targets the protein on the membrane while the trans-membrane domain of Ompa serves as an anchor. MBP is on the externally exposed loops of OmpA, which can be anchored to the outer membrane.

Figure 2: The expression of lpp-OmpA-MBP in the surface of our bacterial. We can see a clear band about 27KD in both SDS-PAGE and Western blotting.
