| Outline of Final Research Achievements |
ATP-binding cassette (ABC) transporters constitute a large superfamily of integral membrane proteins that transport several substrates through cellular membranes using the energy of binding, hydrolysis, and release of ATP. In this study, we investigated the roles of coupling helices (CHs) and the effect of ATP for bacterial ABC transporters MsbA and TM287/288 as targets by molecular simulations. Compering the wild type and CH mutants, we revealed the roles of each CH on conformational changes and the effect of the binding of ATP. These findings provide important insight into the structure-function relationship of ABC transporters.
