| Outline of Final Research Achievements |
In this project, the reconstitution of transmembrane proteins in supported lipid bilayers using cell-free protein synthesis was investigated. Supported bilayers were formed by vesicle fusion, and then protein expression was conducted over these bilayer systems. However, protein folding in supported bilayers was not observed under any experimental conditions tested. The project also aimed at the investigation of properties of supported lipid bilayers because they affect the properties and functions of transmembrane proteins. It was found that the packing density of supported bilayers can change with solution pH. In addition, the defect formation mechanisms in supported bilayers were clarified.
