Twister P1 + T7_RBS + intimin-Nb2 fusion + stem-loop
Introduction
We introduced a self-assembly synthetic adhesion system by transfecting initimin-Nb2 fusion into E. coli. Initimin-Nb2 fusion is composed of a surface display system (intimin) and the coding sequence of a nanobody. The surface display system, which includes a short N-terminal signal peptide to direct its trafficking to the periplasm, a LysM domain for peptidoglycan binding, and a beta-barrel for transmembrane insertion[1], possesses the outer membrane anchoring of the nanobody[2]. We’ve constructed this fusion protein into our ribozyme-assisted polycistronic co-expression system：pRAP.
Usage and Biology
The surface-displayed nanobody can specifically interact with the antigen produced by ribozyme+strong RBS+intimin-Ag2 fusion+stem-loop .In our project, we took full advantage of the Ag-Nb interaction to create a biofilm with a programmable physical structure[3].
