Outline of Final Research Achievements

(1)It was shown that inter-subunit interactions within rotor components is altered under uncoupling state. (2)Recovery of the coupling by the inter-subunit cross-linking has not been observed so far. (3)It was shown that one third of the TFoF1 molecules may be incomplete.(4) A mutant epsilon subunit with higher affinity for ATP was obtained. (5) The physiological significance of the regulation of ATP synthase in Bacillus subtilis was clarified.

Academic Significance and Societal Importance of the Research Achievements

いまだ不明な点の多い、ATP合成酵素の条件的脱共役状態について、さまざまな知見を得ることができた。更に研究を続け分子機構の解明へとつなげたい。
ATP合成酵素の活性調節機構は原核生物と真核生物では異なるため、抗生物質の作用点として注目されている。条件的脱共役も、εサブユニットが構造変化をするバクテリアATP合成酵素のみが持つ性質であると考えられることから、同様に全く新しい抗生物質の作用点として活用することも期待される。
