毒素-抗毒素(TA)模块是指定毒素及其抗毒素的基因对,并且在包括病原体的许多细菌的染色体上发现。在这里,我们报告如何在E。大肠杆菌在液体培养基中和生物膜形成期间对细菌细胞死亡的影响不同。在所有这些系统中,只有TA系统MazEF在液体培养基中和生物膜形成期间介导细胞死亡。在另一个极端,正如我们的研究结果所揭示的,TA系统dinJ-YafQ是独特的,因为它只参与生物膜形成期间的死亡过程。MazEF和dinJ-YafQ控制的细胞死亡似乎通过一种新机制参与生物膜的形成。
Toxin-antitoxin (TA) modules are gene pairs specifying for a toxin and its antitoxin and are found on the chromosomes of many bacteria including pathogens. Here we report how each of five such TA systems in E. coli affect bacterial cell death differently in liquid media and during biofilm formation. Of all these systems, only the TA system mazEF mediated cell death both in liquid media and during biofilm formation. At the other extreme, as our results have revealed here, the TA system dinJ-YafQ is unique in that it is involved only in the death process during biofilm formation. Cell death governed by mazEF and dinJ-YafQ seems to participate in biofilm formation through a novel mechanism.
