Alternative transcription cycle for bacterial RNA polymerase

open access: yesNature Communications, 2020
In the canonical bacterial transcription, both nascent transcript and polymerase dissociate from template DNA. By employing multi-color single-molecule fluorescence imaging, here the authors show that RNA polymerases remain bound to DNA after the ...

Programmable control of bacterial gene expression with the combined CRISPR and antisense RNA system

open access: yesNucleic Acids Research, 2016
A central goal of synthetic biology is to implement diverse cellular functions by predictably controlling gene expression. Though research has focused more on protein regulators than RNA regulators, recent advances in our understanding of RNA folding and

Purification of Bacterial RNA from Infected Macrophages

open access: yesBio-Protocol, 2015
Studying the transcriptome of bacterial pathogens during infection is a very informative and effective tool for discovering genes that contribute to successful infection.

Amniotic fluid from healthy term pregnancies does not harbor a detectable microbial community [PDF]

open access: yes, 2018
Recent studies have conflicting data regarding the presence of intra-amniotic microbiota. Viral communities are increasingly recognized as important although overlooked components of the human microbiota.

Single-Cell RNA Sequencing of Plant-Associated Bacterial Communities

open access: yesFrontiers in Microbiology, 2019
Plants in soil are not solitary, hence continually interact with and obtain benefits from a community of microbes (“microbiome”). The meta-functional output from the microbiome results from complex interactions among the different community members with ...

A Distinct Mechanism to Achieve Efficient Signal Recognition Particle (SRP)-SRP Receptor Interaction by the Chloroplast SRP Pathway [PDF]

open access: yes, 2009
Cotranslational protein targeting by the signal recognition particle (SRP) requires the SRP RNA, which accelerates the interaction between the SRP and SRP receptor 200-fold.

The bacterial enhancer-dependent RNA polymerase

open access: yesBiochemical Journal, 2016
Transcription initiation is highly regulated in bacterial cells, allowing adaptive gene regulation in response to environment cues. One class of promoter specificity factor called sigma54 enables such adaptive gene expression through its ability to lock ...

Assessment of bacterial and viral gut communities in healthy and tumoral colorectal tissue using RNA and DNA deep sequencing

open access: yesCancer Medicine, 2023
Background Colorectal cancer (CRC) is known to present a distinct microbiome profile compared to healthy mucosa. Non‐targeted deep‐sequencing strategies enable nowadays full microbiome characterization up to species level.

Bio-Communication of Bacteria and its Evolutionary Interrelations to Natural Genome Editing Competences of Viruses [PDF]

open access: yes, 2008
Communicative competences enable bacteria to develop, organise and coordinate rich social life with a great variety of behavioral patterns even in which they organise themselves like multicellular organisms.

Toll-like receptor expression in C3H/HeN and C3H/HeJ mice during Salmonella enterica serovar Typhimurium infection [PDF]

open access: yes, 2003
Here, we have investigated the mRNA expression of Toll-like receptor 2 (TLR-2), TLR-4, and MD-2 in spleens and livers of C3H/HeN mice (carrying wild-type TLR-4) and C3H/HeJ mice (carrying mutated TLR-4) in response to Salmonella infection.
