Abstract: 
Listeria monocytogenes is an important zoonotic foodborne pathogen that can tolerate a number of environmental stresses. rsbR, an upstream regulator of the sigma B (SigB) factor, is thought to sense environmental challenges and trigger the SigB pathway. In Bacillus subtilis, two phosphorylation sites in rsbR are involved in activating the SigB pathway and a feedback mechanism, respectively. In this study, the role of rsbR in L. monocytogenes under mild and severe stresses was investigated. Strains with genetic deletion (ΔrsbR), complementation (C-ΔrsbR), and phosphorylation site mutations in the rsbR (rsbR-T175A, rsbR-T209A, and rsbR-T175A-T209A) were constructed to evaluate the roles of these rsbR sequences in listerial growth and survival. SigB was examined at the transcriptional and translational levels. Deletion of rsbR reduced listerial growxth and survival in response to acidic stress. Substitution of the phosphorylation residue rsbR-T175A disabled rsbR complementation, while rsbR-T209A significantly upregulated SigB expression and listerial survival. Our results provide clear evidence that two phosphorylation sites of rsbR are functional in L. monocytogenes under acidic conditions, similar to the situation in B. subtilis.

单核细胞增多性李斯特菌RsbR抗酸应激机制

目的:探明单增李斯特菌RsbR的两个保守磷酸化位点是否影响SigB(sigma B)的表达.
创新点:解析了RsbR在单增李斯特菌中SigB网络调控中的作用.
方法:通过基因缺失、定点突变和回补技术构建rsbR基因缺失株、回补株和回补突变菌株,进行酸应激条件下的生长能力和强酸条件下的存活能力试验,并检测在酸应激下菌株中的SigB基因和蛋白表达的改变情况.
结论:RsbR缺失能够显著降低单增李斯特菌的抗酸应激能力和下调SigB表达,RsbR-175位点是SigB调控途径中RsbT释放的先决条件.
