A hepatitis C virus cis-acting replication element forms a long-range RNA-RNA interaction with upstream RNA sequences in NS5B [PDF]

, 2008
The genome of hepatitis C virus (HCV) contains cis-acting replication elements (CREs) comprised of RNA stem-loop structures located in both the 5' and 3' non-coding regions (NCR), and in the NS5B coding sequence.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Accurately assembling nanopore sequencing data of highly pathogenic bacteria

BMC Genomics
Background Bacterial genome exploration and outbreak analysis rely heavily on robust whole-genome sequencing and bioinformatics analysis. Widely-used genomic methods, such as genotyping and detection of genetic markers demand high sequencing accuracy and

Quantitative RNA pseudouridine landscape reveals dynamic modification patterns and evolutionary conservation across bacterial species

eLife
Pseudouridine (Ψ) modifications are the most abundant RNA modifications; however, their distribution and functional significance in bacteria remain largely unexplored compared to eukaryotic systems.

Host A-to-I RNA editing signatures in intracellular bacterial and single-strand RNA viral infections

Frontiers in Immunology, 2023
BackgroundMicrobial infection is accompanied by remodeling of the host transcriptome. Involvement of A-to-I RNA editing has been reported during viral infection but remains to be elucidated during intracellular bacterial infections.ResultsHerein we ...

Conformational flexibility of bacterial RNA polymerase [PDF]

Proceedings of the National Academy of Sciences, 2002
The structure of Escherichia coli core RNA polymerase (RNAP) was determined by cryo-electron microscopy and image processing of helical crystals to a nominal resolution of 15 Å. Because of the high sequence conservation between the core RNAP subunits, we were able to interpret the

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Regulating Bacterial Transcription with Small RNAs [PDF]

Cold Spring Harbor Symposia on Quantitative Biology, 2006
In recent years, the combinations of computational and molecular approaches have led to the identification of an increasing number of small, noncoding RNAs encoded by bacteria and their plasmids and phages. Most of the characterized small RNAs have been shown to operate at a posttranscriptional level, modulating mRNA stability or translation by base ...
