Dissecting specific and global transcriptional regulation of bacterial gene expression

open access: yesMolecular Systems Biology, 2013
Gene expression is regulated by specific transcriptional circuits but also by the global expression machinery as a function of growth. Simultaneous specific and global regulation thus constitutes an additional—but often neglected—layer of complexity in ...

Post-transcriptional regulation of gene expression in bacterial pathogens by toxin-antitoxin systems [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
Toxin-antitoxin (TA) systems are small genetic elements ubiquitous in prokaryotic genomes that encode toxic proteins targeting various vital cellular functions.

Identification of BvgA-Dependent and BvgA-Independent Small RNAs (sRNAs) in Bordetella pertussis Using the Prokaryotic sRNA Prediction Toolkit ANNOgesic

open access: yesMicrobiology Spectrum, 2021
Noncoding small RNAs (sRNAs) are crucial for the posttranscriptional regulation of gene expression in all organisms and are known to be involved in the regulation of bacterial virulence.

Conformational change of the Bordetella response regulator BvgA accompanies its activation of the B. pertussis virulence gene fhaB

open access: yesComputational and Structural Biotechnology Journal, 2022
The BvgAS two-component system regulates virulence gene expression in Bordetella pertussis. Although precise three-dimensional structural information is not available for the response regulator BvgA, its sequence conservation with E.

Status quo of tet regulation in bacteria

open access: yesMicrobial Biotechnology, 2022
Summary The tetracycline repressor (TetR) belongs to the most popular, versatile and efficient transcriptional regulators used in bacterial genetics. In the tetracycline (Tc) resistance determinant tet(B) of transposon Tn10, tetR regulates the expression

Algorithm for the Reconstruction of Mathematical Frame Models of Bacterial Transcription Regulation

open access: yesMathematics, 2022
Transcription regulation plays an important role in bacterial activity. The operon concept coined by François Jacob and Jacques Monod has had a considerable effect on investigations into gene expression regulation, including modeling.

An Adaptable and Modular Set of Laboratory Exercises Connecting Genotype to Phenotype in Sporulating Bacillus subtilis

open access: yesJournal of Microbiology & Biology Education, 2021
Practical lab exercises that help students draw connections between genotype and phenotype, and make and test predictions about the identity of mutants, are invaluable in college-level cell biology, genetics, and microbiology courses. While many bacteria

Mode of Regulation and the Insulation of Bacterial Gene Expression [PDF]

open access: yesMolecular Cell, 2012
A gene can be said to be insulated from environmental variations if its expression level depends only on its cognate inducers, and not on variations in conditions. We tested the insulation of the lac promoter of E. coli and of synthetic constructs in which the transcription factor CRP acts as either an activator or a repressor, by measuring their input

Epigenetic silencing of host cell defense genes enhances intracellular survival of the rickettsial pathogen Anaplasma phagocytophilum. [PDF]

open access: yesPLoS Pathogens, 2009
Intracellular bacteria have evolved mechanisms that promote survival within hostile host environments, often resulting in functional dysregulation and disease.

Lithium-sensing riboswitch classes regulate expression of bacterial cation transporter genes

open access: yesScientific Reports, 2022
AbstractLithium is rare in Earth’s crust compared to the biologically relevant alkali metal cations sodium and potassium but can accumulate to toxic levels in some environments. We report the experimental validation of two distinct bacterial riboswitch classes that selectively activate gene expression in response to elevated Li+ concentrations.
