Role of the Alternative Sigma Factor ςS in Expression of the AlkS Regulator of thePseudomonas oleovorans Alkane Degradation Pathway... Inés,Canosa,Luis,... - 《Journal of Bacteriology》 被引量: 0发表: 1999年 The cellular concentration of the sigma S subunit of RNA polymerase in Escherichia...
The alternative sigma factor sigma 54 of enteric bacteria, or its homologue in other purple bacteria, is required for transcription of genes whose products have diverse physiological roles. Previous studies have indicated that sigma 54 confers on core RNA polymerase the ability to recognize a specific...
Heoet al.31have suggested that the differences in redox sensitivity of different ZAS proteins are due to the differences in electronegative residues and binding of alternative zinc ions. However, as our data above illustrate, additional zinc ions play little or no role in the redox-sensing ability...
The cointegration relationship between xit and yit is tested by the null hypothesis ρ = 1 and the alternative hypothesis ρ < 1. Empirical framework of inverted U-shaped and N-shaped EKC In the pioneer literature (Grossman and Krueger, 1991; 1995), the traditional EKC hypothesis ...
Briefly, cells were treated, fixed with 4% paraformaldehyde for 30 min, permeabilized with 0.1% Triton X-100 (Sigma-Aldrich, T8787) for 5 min, blocked with 5% BSA in TBST for 1 h, incubated with primary and secondary antibodies, stained with DAPI (AR1177, Boster, China), and visualized...
lactis as an interesting alternative to ADI-PEG20 for future development. Our results show that the L. lactis Lc4 strain has a unique ability to release ADI to the supernatant, in stress-simulating conditions, as compared to Lc2 and Lc3 strains. The ADI pathway in bacteria consists of three...
The extracytoplasmic function sigma factor σVreI of the human pathogen Pseudomonas aeruginosa promotes transcription of potential virulence determinants, including secretion systems and secreted proteins. Its activity is modulated by the VreR anti-σ fa
For these alternative analyses, we used ModelFinder on the partitioned, concatenated dataset, rather than constructing gene trees individually first as for our primary analysis. Our maximum likelihood analyses on nucleotides were primarily based on nucleotide position two due to the presence of ...
(additional file2: Table S1). Previous work has also shown that, in contrast toE. coli, ppGpp does not control RpoS levels inS. Typhimurium during late-log and stationary phase growth [9]. We conjecture that the ppGpp-repression of some of the alternative sigma factor regulons may ...
