The bacterial cell envelope plays essential roles in controlling cell shape, division, pathogenicity, and resistance against external stresses. In Escherichia coli, peptidoglycan (PG) has long been thought to be the primary component that conveys mechanical strength to the envelope. But a recent publication demonstrates the key contribution of the lipoprotein Lpp in defining the stiffness of the cell envelope and its sensitivity to drugs.

肽聚糖以外的细菌细胞力学。

细菌细胞包膜在控制细胞形状，分裂，致病性和对外部压力的抗性中起着至关重要的作用。在大肠杆菌中，肽聚糖（PG）一直被认为是将机械强度传递到外壳的主要成分。但是最近的出版物证明脂蛋白Lpp在定义细胞包膜的硬度及其对药物的敏感性方面的关键作用。
