In Escherichia coli wild-type cells, a mutation at the beta-glucoside regulatory gene (bglR(+) to bglR(-)) leads to simultaneous expression of inducible phospho-beta-glucosidase B (bglB(+)) and a beta-glucoside-specific species of enzyme II (beta-glucoside transport I [bglC(+)]); an additional mutation (bglS(+) to bglS4) allows these enzymes to be formed constitutively. The bgl alleles have been mapped in the following order: pyrE, bglA, bglB, bglS, bglR, bglC, ilvD. The back mutation in the… Expand
The β-Glucoside (bgl) Operon of Escherichia coli Is Involved in the Regulation of oppA, Encoding an Oligopeptide Transporter
The bgl operon of Escherichia coli, encoding the functions necessary for the uptake and metabolism of aryl-β-glucosides, is involved in the regulation of oligopeptide transport during stationary phase and is mediated via gcvA, the activator of the glycine cleavage system, and gcvB, which regulates oppA at the posttranscriptional level.

Diverse pathways for salicin utilization in Shigella sonnei and Escherichia coli carrying an impaired bgl operon
The pathway to achieve salicin utilization is diverse in Shigella sonnei and E. coli strain tree; however, both show cooperation between two silent genetic systems to achieve a new metabolic capability under selection. Expand
In Vivo Expression of the β-Glucoside (bgl) Operon of Escherichia coli Occurs in Mouse Liver
It is demonstrated that expression of the bgl operon occurs in infected mouse liver and suggests a unique role for this operon in vivo. Expand
Evolution of Aromatic β-Glucoside Utilization by Successive Mutational Steps in Escherichia coli
The sequential accumulation of mutations in bglA can confer the ability to hydrolyze the related aromatic β-glucosides esculin and salicin in two steps, underscore the ability of microorganisms to evolve additional metabolic capabilities by mutational modification of preexisting genetic systems under selection pressure, thereby expanding their repertoire of utilizable substrates.

Analysis of the interaction of the LuxR-type transcription factors BglJ and RcsB and antagonism of H-NS mediated silencing in Escherichia coli
Data from Co-immunoprecipitation studies support the model that RcsB forms a heterodimer with BglJ, that the RCSB-BglJ heterodender antagonizes H-NS in bgl, and that it Rcs B-B glJ plays an important role in global gene regulation. Expand
Genome variations in commensal and pathogenic E.coli
A systematic analysis of DNA polymorphisms at the region of bgl/Z5211-Z5214 island encoded systems demonstrated the genetic diversity among the E.coli strains and demonstrated that the sequence variations seen at the bgl promoter region in the CFT073 b gl/Z type strains does not significantly influence the b gl expression in E. coli isolates.

Cell cycle progression in Caulobacter requires a nucleoid-associated protein with high AT sequence recognition
It is shown that GapR only associates with DNA sequences of high adenine and thymine (AT) content, colocating with cell cycle master regulators that control genes mediating swarmer cell development, and proposed that Caulobacter has co-opted a nucleoid-associated protein with high AT recognition to serve as a mediator of cell cycle progression.

Deconstructing the structural conservation of distantly related bacterial nucleoid-associated proteins using functional chimeras
This work has identified a sequence element unique to GapR that enables assembly into its tetrameric state and showed that GapR is capable of bridging DNA molecules in vitro. Expand
The Nucleoid-Associated Protein GapR Uses Conserved Structural Elements To Oligomerize and Bind DNA
The structural elements involved in oligomerization and DNA binding of a newly discovered NAP in Caulobacter crescentus are identified and the demonstration that structural elements are conserved in evolutionarily distant and functionally distinct NAPs is demonstrated. Expand
Protein targeting via mRNA in bacteria.
Although the underlying mechanisms for transcript localization in bacteria are yet to be unraveled, it is now obvious that intracellular localization of mRNA is a common mechanism to spatially localize proteins in both eukaryotes and prokaryotes. Expand
