Sigma因子70 RpoD通过调节细胞运动性、耐氧化应激能力,并调控Xanthomonas oryzae pv. oryzae中hrpG和hrpX的表达,从而对致病性做出贡献。 期刊名称:Journal of Integrative Agriculture 期刊IF:4.8/Q1 项目材料:水稻白叶枯病菌 爱基百客提供技术服务:CUT&Tag 合作单位:南京农业大学 Title(E):Sigma factor 70 RpoD contr...
The cell penetrating peptide-mediated antibacterial RNA polymerase sigma 70 factor gene rpoD which is antisense nucleic acid of a specificity target can selectively inhibit the expression of in-vivo ropD genes of Gram-negative bacterium (containing sensitive and multidrug resisting clinical pathogenicity ...
coli strain library with all non-essential genes systematically deleted, we unexpectedly discovered upon whole-genome sequencing that the improved phenotype was not conferred by the deleted genes but by various subtle alterations in the "housekeeping" sigma 70 factor (RpoD). When analyzing effects of...
Sigma factorsin E. coli: σ70(RpoD) –σA– the "housekeeping"sigma factoror also called as primarysigma factor, transcribes most genes in growing cells. WikiMatrix SigB, an alternativesigma factor, up-regulates Vir genes in the intestines, whereas PrfA up-regulates gene expression when the...
RNA polymerase sigma 70 (also known as RNA pol sigma70 and rpoD) is a part of a family of sigma factor subunits that are required for specificpromoter recognition and initiation. RNA pol sigma 70 is the major housekeeping sigma factorresponsible for RNA polymerase recognition out of the ...
4)胞外功能sigma因子(extracytoplasmicfunctionsigmafactor,ECFsigmafactor):此类sigma因子的数量种类最多,约占所有sigma因子的 60%,同类因子之间保守性较低,其功能为响应细胞外环境信号,例如假单胞菌属的AlgU响应干燥和渗透压信号,调控细菌糖被的合成;枯草芽孢杆菌的SigW、SigX、SigY和SigZ响应高温环境,调控芽孢的...
E. coliuses varioussigma factorsto recruitRNApolymerase (RNAP) to initiate transcription and regulate a specific set of genes/operons (Feklístov et al., 2014). These include the house keeping sigma factor σ70 (RpoD), heat shock sigma factor σ32 (RpoH), extreme heat stress sigma factor...
σ70sigma factor (RpoD) and RpoS tend to be similar (Hengge-Aronis, 2002b). One factor that is important in determining RpoS promoter specificity is the sequence of the extended -10 region. In agreement with this, Eggers et al. confirmed that the -12 to -16 region provided RpoS ...
In addition, we searched putative RpoD-dependent genes based on these promoter elements on the whole genome sequence of phytoplasmas using in silico tools. The phytoplasmal RpoD seems to mediate the transcription of not only many housekeeping genes as the principal sigma factor, but also the ...
