WebDec 1, 2006 · Our current model for the regulation of this response is that the PstSCAB transporter senses P i levels and communicates through the PhoU protein to the histidine kinase PhoR, which controls the phosphorylation of the response regulator PhoB. WebJan 1, 2006 · The phoU gene is the last cistron in the pstSCAB–phoU operon and functions as a negative regulator of the Pho regulon. The authors previously identified a phoU mutant of extraintestinal pathogenic Escherichia coli strain CFT073 and demonstrated that this mutant was attenuated for survival in the murine model of ascending urinary tract …

WebMycoplasma genitalium is expected to metabolize RNA using unique pathways because its minimal genome encodes very few ribonucleases. In this work, we report that the only exoribonuclease identified in M. genitalium, RNase R, is able to remove tRNA 3′-trailers and generate mature 3′-ends. Several sequence and structural features of a tRNA precursor … WebExpression of the Pho regulon in Escherichia coli is induced in response to low levels of environmental phosphate (Pi). Under these conditions, the high-affinity PstSCAB2 protein …
WebNov 15, 2012 · Phosphate, in terms of cellular content, is the fifth most important element. Its homeostasis is controlled by the two-component system (TCS) PhoBR. The pstSCAB-phoU operon, encoding the phosphate specific transport system (Pst), is among the genes regulated by PhoBR. It mediates phosphate acquisition and is required for virulence in … WebMay 11, 2015 · Genetic studies indicate that PhoB activity is repressed by the combined action of PhoR, PhoU, and the PstSCAB phosphate transport system in the presence of …
WebThe genome of the marine Synechococcus sp. WH8102 displays a minimal regulatory network yet physiological and molecular responses of this organism are tuned to episodic limitation for nitrogen and phosphorus. Microarray analyses have demonstrated a key role for the two-component regulatory system, PhoBR, in the regulation of P transport and … WebMay 11, 2015 · Genetic studies indicate that PhoB activity is repressed by the combined action of PhoR, PhoU, and the PstSCAB phosphate transport system in the presence of high extracellular phosphate concentrations [ 20] ( Fig 1 ). Mutations in phoU, phoR, or pstSCAB result in de-repression of the regulon.
