Abstract

Summary: The FimH adhesin of type 1 fimbriae has been tested as a display system for heterologous protein segments on the surface of . This was carried out by introduction of restriction site handles sites) in two different positions in the gene, followed by in-frame insertion of heterologous DNA segments encoding two reporter sequences. In the selected positions such insertions did not significantly alter the function of the FimH protein with regard to surface location and adhesive ability. The system seemed to be quite flexible, since chimeric versions of the FimH adhesin containing as many as 56 foreign amino acids were transported to the bacterial surface as components of the fimbrial organelles. Furthermore, the foreign protein segments were recognized by insert-specific antibodies when expressed within chimeric proteins on the surface of the bacteria. The results from this feasibility study point to the possibility of using the FimH adhesin as a general surface display system for sizeable protein segments.
