Operons [PDF]

open access: yesCellular 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

Diel gene expression improves software prediction of cyanobacterial operons [PDF]

open access: yesPeerJ, 2022
Cyanobacteria are important participants in global biogeochemical process, but their metabolic processes and genomic functions are incompletely understood.

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

open access: yesFrontiers 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

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.

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 ...

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.

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 ...

Rules of Expansion: an Updated Consensus Operator Site for the CopR-CopY Family of Bacterial Copper Exporter System Repressors

open access: yesmSphere, 2020
Copper is broadly toxic to bacteria. As such, bacteria have evolved specialized copper export systems (cop operons) often consisting of a DNA-binding/copper-responsive regulator (which can be a repressor or activator), a copper chaperone, and a copper ...

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.
