| Outline of Final Research Achievements |
In this study, we investigated the roles of proton pump ATPases in the principal causative agent of human dental deseases, S. mutans and P. gingivalis.
We suggested that F-ATPase is an essential role in acid tolerance in S. mutans, and proton gradient and A-ATPase are important for the growth of P. gingivalis. We also found various inhibitors of bacterial proton pump ATPase and suggested their inhibitory mechanism and binding sites.
Furthermore, we analyze the function of lysosomal proton pump V-ATPase in mammalian osteoclast, which associates with bone resorption in periodontal diseases. We found a novel role for the V-ATPase in secretory lysosome trafficking and an unexpected mechanistic link with Rab GTPases.
