Over-expression of multidrug efflux pumps of the Resistance Nodulation Division (RND) protein super family counts among the main causes for microbial resistance against pharmaceuticals. Understanding the molecular basis of this process is one of the major challenges of modern biomedical research, involving a broad range of experimental and computational techniques. Here we review the current state of RND transporter investigation employing molecular dynamics simulations providing conformational samples of transporter components to obtain insights into the functional mechanism underlying efflux pump-mediated antibiotics resistance in Escherichia coli and Pseudomonas aeruginosa.
耐药结节化分裂(RND)蛋白超家族多药外排泵的过度表达是微生物对药物产生耐药性的主要原因之一。了解这一过程的分子基础是现代生物医学研究的主要挑战之一,涉及广泛的实验和计算技术。在这里,我们回顾了利用分子动力学模拟对RND转运蛋白的研究现状,该模拟提供了转运蛋白组件的构象样本,以深入了解大肠杆菌和铜绿假单胞菌中由外排泵介导的抗生素耐药性的功能机制。
