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

open access: yesVirus 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

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

The BvgAS Regulon of Bordetella pertussis

open access: yesmBio, 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.

Relationship between the Chromosome Structural Dynamics and Gene Expression—A Chicken and Egg Dilemma?

open access: yesMicroorganisms, 2022
Prokaryotic transcription was extensively studied over the last half-century. A great deal of data has been accumulated regarding the control of gene expression by transcription factors regulating their target genes by binding at specific DNA sites ...

Transcriptome profiling analysis reveals metabolic changes across various growth phases in Bacillus pumilus BA06

open access: yesBMC Microbiology, 2017
Background Bacillus pumilus can secret abundant extracellular enzymes, and may be used as a potential host for the industrial production of enzymes. It is necessary to understand the metabolic processes during cellular growth.
