| Outline of Final Research Achievements |
(1) Biochemical analysis of Bacillus subtilis F1-ATPase (BF1) revealed that BF1 is strongly inhibited by MgADP inhibition and the "inhibitory" epsilon subunit acts as an activator in BF1. (2) It was revealed that the strong MgADP inhibition of BF1 is not due to the low ATP binding affinity of noncatalytic sites. (3) Overexpression system of BFoF1 was successfully constructed. (4) Bacillus subtilis strain containing an ATP-sensor protein (ATeam) was constructed. (5) Physiological conditions where the regulation of BFoF1 by the epsilon subunit is prominent were revealed.
