摘    要:革兰氏阴性细菌的外膜由脂多糖、磷脂、外膜蛋白和脂蛋白等成分组成,是细菌抵御外界有害物质的首要物理屏障,与细菌致病性和耐药性密切相关.外膜各组分依赖特定的系统进行跨膜转运,包括脂多糖转运系统(lipopolysaccharide transport, Lpt)、脂质不对称维持系统(maintenance of lipid asymmetry, Mla)、β-桶状装配机器(β-barrel assembly machinery,Bam)以及脂蛋白定位系统(localization of lipoprotein,Lol).这些系统能够保证细菌外膜的完整与稳定,被视为维持细菌生命活动的"命门".因此,本文系统地综述革兰氏阴性细菌外膜主要成分的跨膜转运系统结构与功能,并对其未来研究方向进行展望,为新型靶向抗菌类药物研发提供新的思路.

关 键 词:革兰氏阴性细菌  外膜主要成分  跨膜转运系统结构与功能
