| Outline of Final Research Achievements |
In this project, I established heterologous expression, microscopic single-molecule analysis and X-ray crystallographic systems for bovine F1-ATPase which has high structural similarity to human F1. By using the systems, effects of resveratrol, which has been suggested to have positive effects of extending lifetime and curing adult diseases of eukaryotes, have been analyzed as a model inhibitor for mammalian F1. As a result, resveratrol was suggested to inhibit the ATP-synthesis turnover by preventing the elementary step of product phosphate-binding by binding to the cleft formed between the rotor and stator subunits of bovine F1. This finding would become a theoretical basis to artificially control the energy system of mammalian species in future.
