外排泵是导致多重耐药性的膜蛋白。在革兰氏阴性细菌中,其中一些泵形成与外膜通道和周质膜融合蛋白相关的复杂的三联组件。这些三部分机器跨越膜和周质空间,并且它们从细菌中挤出化学上不同的有毒底物。在本章中,我们总结了目前对三方多药物外排组件的结构、功能和调节的理解。 (C) 2018 年巴斯德研究所。由 Elsevier Masson SAS 出版。版权所有。
Efflux pumps are membrane proteins which contribute to multi-drug resistance. In Gram-negative bacteria, some of these pumps form complex tripartite assemblies in association with an outer membrane channel and a periplasmic membrane fusion protein. These tripartite machineries span both membranes and the periplasmic space, and they extrude from the bacterium chemically diverse toxic substrates. In this chapter, we summarise current understanding of the structural architecture, functionality, and regulation of tripartite multi-drug efflux assemblies. (C) 2018 Institut Pasteur.
