mSphere, 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 ...

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

CadC-mediated activation of the cadBA promoter in Escherichia coli [PDF]
, 2005 The transcriptional activator CadC in Escherichia coli, a member of the ToxR-like proteins, activates transcription of the cadBA operon encoding the lysine decarboxylase CadA and the lysine-cadaverine antiporter CadB. cadBA is induced under conditions of

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),

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

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 ...
