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

open access: yesFrontiers 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

open access: yesmSystems, 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

open access: yesMicroorganisms, 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 ...

Operon-SEQer ensemble tested against new data sets.

open access: yes, 2022
Recall (blue) and specificity (red) of the Operon-SEQer ensemble with algorithm agreement cutoffs of 1–6 for operon pair calls for the new data set from (A) B. subtilis, (B) P. syringiae, and (C) M. tuberculosis. (TIF)

Operon-SEQer is best used as an ensemble of methods and finds operons not annotated by the standard but detected by PACBIO SMRTseq.

open access: yes, 2022
(A) AUC scores of OperonSEQer operon pair calls on MicrobesOnline E.coli operons, and both OperonSEQer and MicrobesOnline operon pair calls on SMRT-seq E.coli operons.

Operon-SEQer features and performance across the various algorithms used.

open access: yes, 2022
(A) Spearman’s correlation coefficients between the features considered for use in machine learning and operon pair calls made by MicrobesOnline across 7-species (see main text). KW = Kruskal Wallis statistic.

Evaluation of Biofilm Formation and Presence of Genes in Clinical Isolates [PDF]

open access: yesOsong Public Health and Research Perspectives, 2018
Objectives Biofilm formation is one of the important features of Staphylococcus epidermidis, particularly in nosocomial infections. We aimed to investigate the biofilm production by phenotypic methods and the presence of ica genes in S epidermidis ...

Operons in eukaryotes [PDF]

open access: yesBriefings in Functional Genomics and Proteomics, 2004
It was thought that polycistronic transcription is a characteristic of bacteria and archaea, where many of the genes are clustered in operons composed of two to more than ten genes. By contrast, the genes of eukaryotes are generally considered to be monocistronic, each with its own promoter at the 5' end and a transcription terminator at the 3' end ...

Fate of the H-NS-repressed bgl operon in evolution of Escherichia coli. [PDF]

open access: yes, 2009
In the enterobacterial species Escherichia coli and Salmonella enterica, expression of horizontally acquired genes with a higher than average AT content is repressed by the nucleoid-associated protein H-NS.

Transcriptome Landscape of Mycobacterium smegmatis

open access: yesFrontiers in Microbiology, 2017
The non-pathogenic bacterium Mycobacterium smegmatis mc2155 has been widely used as a model organism in mycobacterial research, yet a detailed study about its transcription landscape remains to be established. Here we report the transcriptome, expression
