How do bacteria assemble transmembrane β-barrels into their outer membrane in the absence of an energy source? New structures and experiments from Doyle et al. suggest that the β-barrel assembly machinery (BAM) co-opts the power of membrane elastic tension to help complete the folding of β-barrel outer membrane proteins.
在没有能源的情况下,细菌是如何将跨膜β桶组装到它们的外膜中的?多伊尔等人的新结构和实验表明,β桶组装机制(BAM)利用膜弹性张力的能量来帮助完成β桶外膜蛋白的折叠。
