The pho regulons of bacteria
WebbSome bacteria retreat to extreme niches and live on a metabolic fringe. Others live on the move, constantly altering gene expression in response to metabolic changes. Still others take a more long-term approach and construct complex strategies to survive, integrating multiple pathways, regulons and macromolecular assemblies. Webb1 maj 2002 · When Bacillus subtilis is subjected to phosphate starvation, the Pho and sigma (B)-dependent general stress regulons are activated to elicit, respectively, specific …

Webb—Bacterial Pho regulons contain genes whose products are involved in the transport and assimilation of inorganic phosphate. The expression of these genes is regulated by a … Webb3 jan. 2012 · Regulons, as groups of transcriptionally co-regulated operons, are the basic units of cellular response systems in bacterial cells. While the concept has been long and widely used in bacterial studies since it was first proposed in 1964, very little is known about how its component operons are arranged in a bacterial genome. We present a …
Webbregulation in bacterial genomes. In this work, we identified binding sites and reconstructed regulons for 33 orthologous groups of transcription factors (TFs) in 196 reference genomes from 21 taxonomic groups of Proteobacteria. Overall, we predict over 10,600 TF binding sites and identified more than 15,600 target genes for 1,896 Webb31 jan. 2008 · The Pho regulon is a global regulatory circuit involved in bacterial phosphate management (Wanner, 1993, 1996). It has been best studied in model cells like Escherichia coli and Bacillus subtilis . In E. coli , the Pho regulon is comprised of at least 47 genes ( Wanner et al. , 1996 ; Han et al. , 1999 ; Suziedeliene et al. , 1999 ; Harris et al. , 2001 ; …
WebbWe computationally predict operons in the Synechococcus sp. WH8102 genome based on three types of genomic data: intergenic distances, COG gene functions and phylogenetic profiles. In the proposed method, we first estimate a log-likelihood distribution for each type of genomic data, and then fuse these distribution information by a perceptron to … WebbTo test whether yaeB influenced the growth of S.Typhimurium in macrophages, the growth rate of the yaeB mutant strain in RAW264.7 cells was examined. First, deletion of the y ae B gene did not affect bacterial growth in vitro ().However, the growth rate of the yaeB mutant in RAW264.7 cells was reduced 3.0-fold (Figure 1A) compared with that in the wild-type …
Webb30 nov. 2012 · The phosphate-specific transport operon, pstSCAB-phoU, of Gram-negative bacteria is an essential part of the Pho regulon. Its key roles are to encode a high-affinity inorganic phosphate transport system and to prevent activation of PhoB in phosphate-rich environments. In general, mutations in pstSCAB-phoU lead to the constitutive expression …
