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

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 ...

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.

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.

Gene Gangs of the Chloroviruses: Conserved Clusters of Collinear Monocistronic Genes

open access: yesViruses, 2018
Chloroviruses (family Phycodnaviridae) are dsDNA viruses found throughout the world’s inland waters. The open reading frames in the genomes of 41 sequenced chloroviruses (330 ± 40 kbp each) representing three virus types were analyzed for evidence of ...

A Microorganism Transcriptional Regulation Algorithm Based on Generalized Regression Neural Network [PDF]

open access: yesInternational Journal Bioautomation, 2019
Considering the importance of operon in microorganism transcriptional regulation, this paper sets up a new operon prediction model based on artificial neural network (ANN). Specifically, multiple genome information, ranging from intergenic distance (IGD),

Copper Chaperone CupA and Zinc Control CopY Regulation of the Pneumococcal cop Operon

open access: yesmSphere, 2017
Any metal in excess can be toxic; therefore, metal homeostasis is critical to bacterial survival. Bacteria have developed specialized metal import and export systems for this purpose.

The role of the Staphylococcal VraTSR regulatory system on vancomycin resistance and vanA operon expression in vancomycin-resistant Staphylococcus aureus. [PDF]

open access: yesPLoS ONE, 2014
Vancomycin is often the preferred treatment for invasive methicillin-resistant Staphylococcus aureus (MRSA) infection. With the increase in incidence of MRSA infections, the use of vancomycin has increased and, as feared, isolates of vancomycin-resistant
