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-mapper: a web server for precise operon identification in bacterial and archaeal genomes

open access: yesBioinform., 2018
Summary Operon-mapper is a web server that accurately, easily and directly predicts the operons of any bacterial or archaeal genome sequence. The operon predictions are based on the intergenic distance of neighboring genes as well as the functional ...

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 ...

Exploiting rRNA Operon Copy Number to Investigate Bacterial Reproductive Strategies

open access: yesNature Microbiology, 2016
The potential for rapid reproduction is a hallmark of microbial life, but microbes in nature must also survive and compete when growth is constrained by resource availability.

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

Operon Prediction Model Based on Markov Clustering Algorithm [PDF]

open access: yesInternational Journal Bioautomation, 2019
There are many operon prediction models, but few methods can be applied to the operon prediction of new sequencing species effectively. In this paper, an operon prediction model based on Markov clustering algorithm is proposed.

Microbiota profiling with long amplicons using Nanopore sequencing: full-length 16S rRNA gene and the 16S-ITS-23S of the rrn operon

open access: yesbioRxiv, 2018
Background Profiling microbiome on low biomass samples is challenging for metagenomics since these samples are prone to present DNA from other sources, such as the host or the environment.

The mbo operon is specific and essential for biosynthesis of mangotoxin in Pseudomonas syringae. [PDF]

open access: yesPLoS ONE, 2012
Mangotoxin is an antimetabolite toxin produced by certain Pseudomonas syringae pv. syringae strains. This toxin is an oligopeptide that inhibits ornithine N-acetyl transferase, a key enzyme in the biosynthesis of ornithine and arginine.

SMRT-Cappable-seq reveals complex operon variants in bacteria

open access: yesNature Communications, 2018
Current methods for genome-wide analysis of gene expression require fragmentation of original transcripts into small fragments for short-read sequencing. In bacteria, the resulting fragmented information hides operon complexity.

Vulnerabilities in Yersinia pestis caf operon are unveiled by a Salmonella vector. [PDF]

open access: yesPLoS ONE, 2012
During infection, Yersinia pestis uses its F1 capsule to enhance survival and cause virulence to mammalian host. Since F1 is produced in large quantities and secreted into the host tissues, it also serves as a major immune target.
