Transcriptome Landscape of Mycobacterium smegmatis
Frontiers 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

Briefings 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]
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.

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 ...

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
