===Introduction===

We introduced a self-assembly synthetic adhesion system by transfecting intimin-Ag2 fusion into ''E. coli''. Intimin-Ag2 fusion is composed of a surface display system(intimin) and the coding sequence of an antigen. 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<ref>Piñero-Lambea, C., Bodelón, G., Fernández-Periáñez, R., Cuesta, A.

Twister P1 + T7_RBS + intimin-Ag2 fusion + stem-loop

contributed by Fudan iGEM 2023


Similar to BBa_K4765105, we replaced Ag3 with Ag2 in order to interact with BBa_K4765104 to create a biofilm.
