| Outline of Final Research Achievements |
Multidrug efflux pumps belonging to the RND superfamily from multiple Gram-negative bacteria have been cloned and expressed, and mutations have been introduced after meticulously studying the differences and similarities of hundreds of pumps. The results show interesting novel findings relevant and important to the field of multidrug resistance regarding the function of RND-type multidrug efflux pumps, their evolution, their conservation, and their function. During this research period, we have published research papers (as well as review articles) in multiple peer-reviewed journals.
