| Outline of Final Research Achievements |
Effect of membrane potential on the structure and dynamics of membrane proteins must be important for elucidating their molecular mechanisms such as generation of action potential in a nerve cell. In this study, we aimed to develop a new technique of infrared spectroscopy for analyzing changes in a protein structure and its internal hydrogen bonds under the membrane potential. Surface-enhancement of infrared absorption and reconstitution of membrane proteins have been examined. We obtained several results useful for conducting infrared spectroscopy on membrane proteins under existence of the membrane potential in future.
