Revelation of core promoter elements and bidirectional regulation of Geminivirus genes in Escherichia coli [PDF]

Virus Research
Several geminiviruses have been show to possess cross-kingdom gene expression capability. In addition, the intergenic region (IR) of geminivirus genomes is known to regulate the transcription of viral early genes (complementary-sense, C-sense) and late ...

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

Microbiology 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

Computational 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

Microbial 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

Mathematics, 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

Journal 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

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

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

The metabolic enzyme AdhE controls the virulence of Escherichia coli O157:H7 [PDF]

, 2014
Classical studies have focused on the role that individual regulators play in controlling virulence gene expression. An emerging theme, however, is that bacterial metabolism also plays a key role in this process.

The BvgAS Regulon of Bordetella pertussis

mBio, 2017
Nearly all virulence factors in Bordetella pertussis are activated by a master two-component system, BvgAS, composed of the sensor kinase BvgS and the response regulator BvgA.
