Eukaryotic Acquisition of a Bacterial Operon
bioRxiv, 2018 Operons are a hallmark of bacterial genomes, where they allow concerted expression of multiple functionally related genes as single polycistronic transcripts.

Gene Gangs of the Chloroviruses: Conserved Clusters of Collinear Monocistronic Genes
Viruses, 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 ...

Operon Gene Order Is Optimized for Ordered Protein Complex Assembly
Cell Reports, 2016 Summary The assembly of heteromeric protein complexes is an inherently stochastic process in which multiple genes are expressed separately into proteins, which must then somehow find each other within the cell.

A Microorganism Transcriptional Regulation Algorithm Based on Generalized Regression Neural Network [PDF]
International 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
mSphere, 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]
PLoS 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

Decreases in average bacterial community rRNA operon copy number during succession
The ISME Journal, 2015 Trait-based studies can help clarify the mechanisms driving patterns of microbial community assembly and coexistence. Here, we use a trait-based approach to explore the importance of rRNA operon copy number in microbial succession, building on prior ...

Nucleic Acids Research, 2015 Ribosomal RNA (rrn) operons, characteristically present in several copies in bacterial genomes (7 in E. coli), play a central role in cellular physiology. We investigated the factors determining the optimal number of rrn operons in E.
