Coordination of the Fe-S cluster biogenesis network by the sRNA RyhB in E. coli [PDF]

RNA Biology
Iron (Fe) plays critical roles as enzyme cofactor involved in key biological processes but can also lead to toxicity by catalysing the formation of highly damaging reactive oxygen species.

Stoichiometry of the Gene Products From the Tetrachloroethene Reductive Dehalogenase Operon pceABCT

Frontiers in Microbiology, 2022
Organohalide respiration (OHR) is a bacterial anaerobic process that uses halogenated compounds, e.g., tetrachloroethene (PCE), as terminal electron acceptors.

Multiplexed mRNA assembly into ribonucleoprotein particles plays an operon-like role in the control of yeast cell physiology

eLife, 2021
Prokaryotes utilize polycistronic messages (operons) to co-translate proteins involved in the same biological processes. Whether eukaryotes achieve similar regulation by selectively assembling and translating monocistronic messages derived from different

Reporter Gene-Based qRT-PCR Assay for Rho-Dependent Termination In Vivo

Cells, 2023
In bacteria, the Rho protein mediates Rho-dependent termination (RDT) by identifying a non-specific cytosine-rich Rho utilization site on the newly synthesized RNA. As a result of RDT, downstream RNA transcription is reduced.

Operons [PDF]

Cellular and Molecular Life Sciences, 2009
Operons (clusters of co-regulated genes with related functions) are common features of bacterial genomes. More recently, functional gene clustering has been reported in eukaryotes, from yeasts to filamentous fungi, plants, and animals. Gene clusters can consist of paralogous genes that have most likely arisen by gene duplication. However, there are now

Internal Promoters and Their Effects on the Transcription of Operon Genes for Epothilone Production in Myxococcus xanthus

Frontiers in Bioengineering and Biotechnology, 2021
The biosynthetic genes for secondary metabolites are often clustered into giant operons with no transcription terminator before the end. The long transcripts are frangible and the transcription efficiency declines along with the process.

Divide and conquer: genetics, mechanism, and evolution of the ferrous iron transporter Feo in Helicobacter pylori

Frontiers in Microbiology, 2023
IntroductionFeo is the most widespread and conserved system for ferrous iron uptake in bacteria, and it is important for virulence in several gastrointestinal pathogens. However, its mechanism remains poorly understood.

FADU: a Quantification Tool for Prokaryotic Transcriptomic Analyses

mSystems, 2021
Quantification tools for RNA sequencing (RNA-Seq) analyses are often designed and tested using human transcriptomics data sets, in which full-length transcript sequences are well annotated.

The Exploration of Novel Regulatory Relationships Drives Haloarchaeal Operon-Like Structural Dynamics over Short Evolutionary Distances

Microorganisms, 2020
Operons are a dominant feature of bacterial and archaeal genome organization. Numerous investigations have related aspects of operon structure to operon function, making operons exemplars for studies aimed at deciphering Nature’s design principles for ...
