革兰氏阴性菌的外膜(OM)含有大量β-桶外膜蛋白(OMP),其对细胞存活和毒力起许多作用。这些外膜蛋白的生物发生是由β-桶组装机制(BAM)复合物介导的,该复合物由五种组分组成,包括介导OM内插入酶功能的必需核心组分BamA。BamA的晶体结构最近已被报道来自三个不同的物种,包括淋病奈瑟菌的全长结构。突变和功能研究确定了BamA内的几种构象变化,这些变化是功能所需的,这为阐明BamA和BAM复合物如何在OM中折叠和插入新的OMP提供了重大进展。
The outer membranes (OM) of Gram-negative bacteria contain a host of β-barrel outer membrane proteins (OMPs) which serve many functions for cell survival and virulence. The biogenesis of these OMPs is mediated by the β-barrel assembly machinery (BAM) complex which is composed of five components including the essential core component called BamA that mediates the insertase function within the OM. The crystal structure of BamA has recently been reported from three different species, including a full-length structure from Neisseria gonorrhoeae. Mutagenesis and functional studies identified several conformational changes within BamA that are required for function, providing a significant advancement towards unraveling exactly how BamA and the BAM complex are able to fold and insert new OMPs in the OM.
