讲座中文简介:抗药性是全球面临的一个严重的威胁。抗药性由多种机制造成,其中核糖体保护是近年来新发现的一种重要机制。GAO的实验室发现一类新型ATP结合蛋白与核糖体保护依赖的抗药性密切相关。本报告将系统介绍该家族蛋白的生化、分子生物学、结构生物学研究进展及其相应药物设计策略。

Abstract: Current antibiotic resistance crisis urgently requires 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. The ribosome is one of the richest targets for over half of clinically used antibiotics. Recently, we identified a few ATP-binding cassette family proteins that can confer resistance across species to various antibiotic classes through unknown mechanisms. In this talk, I will be presenting our recent progress towards a better understanding of drug resistance involving ribosome protection. Elucidating this mechanism will enable us to rational design improved antimicrobial agents that overcome multidrug-resistant bacteria. Finally, I will briefly introduce molecular mechanism of cyclic di-GMP regulation of bacterial chemotaxis via a PilZ adaptor protein.
