翻译的忠实性是通过生活中所有三个领域的多个质量控制步骤来维持的。由于基因突变和外部压力,翻译错误(误译)增加。严重的误译通常是有害的,但在某些情况下,适度的误译可能是有利的。迄今为止,很少有人知道翻译保真度和宿主-病原体相互作用之间的联系。肠道沙门氏菌可以在全身或慢性感染期间由于胆汁抵抗而在胆囊中存活。在这里,我们表明,增加翻译保真度有助于适应沙门氏菌胆盐暴露后,和改善健身取决于细胞内三磷酸腺苷(ATP)的水平增加。因此,我们的工作揭示了一个以前未知的联系之间的翻译保真度和细菌适应性胆汁压力。
Translational fidelity is maintained by multiple quality control steps in all three domains of life. Increased translational errors (mistranslation) occur due to genetic mutations and external stresses. Severe mistranslation is generally harmful, but moderate levels of mistranslation may be favored under certain conditions. To date, little is known about the link between translational fidelity and host–pathogen interactions. Salmonella enterica can survive in the gall bladder during systemic or chronic infections due to bile resistance. Here we show that increased translational fidelity contributes to the fitness of Salmonella upon bile salt exposure, and the improved fitness depends on an increased level of intracellular adenosine triphosphate (ATP). Our work thus reveals a previously unknown linkage between translational fidelity and bacterial fitness under bile stress.
