Abstract

The bacterial stressosome is a supramolecular multiprotein complex that acts as a critical signal integration and transduction hub, orchestrating cellular responses to environmental stimuli. Recent studies have resolved near-atomic stressosome structures from various bacterial species, revealing assemblies that should be capable of altering their configuration in response to external changes. Further genetic, biochemical, and cell biology research has elucidated interactions and phosphorylation status within the stressosome complex as well as its subcellular localization and mobility within living cells. These insights enhance our comprehension of the stressosome pathways and their roles in directing various survival responses during environmental stress.

细菌应激体的分子结构和功能
细菌应激体是一种超分子多蛋白复合物,是重要的信号整合和转导枢纽,协调细胞对环境刺激的反应。最近的研究已经解析了不同细菌物种的近原子应激体结构,揭示了应激体能够根据外部变化改变其构型的集合体。进一步的遗传、生化和细胞生物学研究阐明了应激体复合物内部的相互作用和磷酸化状态,以及它在活细胞内的亚细胞定位和流动性。这些见解加深了我们对应激体通路及其在环境压力下指导各种生存反应的作用的理解。
