报告摘要

Current antimicrobial resistance crisis urgently requires a better understanding of drug resistance mechanisms and effectively targeted drug discovery. A wide range of mechanisms could mediate antibiotic resistance, which is currently one of the biggest threats to global health and food security. We have determined several structures of ribosome complexes that offers insight into action mechanism of antibiotic as well as rationalizes mutations resulting in resistance. In particular, the newly emerged ATP-binding cassette family proteins (ABC-F) can confer resistance across species to various antibiotic classes through unknown mechanisms.  Elucidating these mechanisms will enable us to rational design improved antimicrobial agents that overcome multidrug-resistant bacteria. On the other hand, antibiotics could help us trap ribosome in certain state so that the structure can be reconstructed and visualized. In this talk, I will be presenting our recent progress towards a better understanding of action mechanisms of antibiotic and drug resistance involving ribosome protection, protein translation and regulation.
