| Outline of Final Research Achievements |
This study aimed to establish the in vitro docking (IVD) method in the magnetotactic bacterium towards the development of the functional composites of bacterial magnetic particles (BacMPs) and human-derived membrane proteins. In the IVD method, recombinant proteins (including membrane proteins) expressed in the periplasmic space of the magnetotactic bacterium were assembled onto BacMPs, which were separately synthesized in the identical bacterium, with the aid of docking protein pairs after cell disruption. Several types of docking protein pairs were examined for the IVD method. Subsequently, as a proof-of-concept, thyroid stimulating hormone receptor (TSHR) was displayed on the BacMPs through the IVD method. In addition, the minimum expression system was established in the magnetotactic bacterium for appropriate protein folding, which could be beneficial for functional expression of recombinant proteins.
