Type II toxin/antitoxin system genes expression in persister cells of Klebsiella pneumoniae [PDF]
, 2020 Objective: Persistence is a subpopulation of bacteria that can tolerate high doses of antibiotics by undergoing a period of dormancy. This study aimed to investigate the hypothetical role of toxin/antitoxin systems in persister cell formation of ...

Characterization of the interaction and cross-regulation of three Mycobacterium tuberculosis RelBE modules. [PDF]
PLoS ONE, 2010 RelBE represents a typical bacterial toxin-antitoxin (TA) system. Mycobacterium tuberculosis H37Rv, the pathogen responsible for human tuberculosis, contains three RelBE-like modules, RelBE, RelFG, and RelJK, which are at least partly expressed in human ...

New Phytologist, EarlyView.Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Bacterial type I toxin-antitoxin systems [PDF]
RNA Biology, 2012 Toxin-antitoxin (TA) loci encode two-component systems that consist of a stable "toxin" whose ectopic overexpression either kills cells or confers growth stasis, and an unstable "antitoxin". TA systems have been initially discovered on plasmids, where they confer stability of maintenance through post-segregational killing (PSK). Plasmid loss results in

The MazEF Toxin-Antitoxin System Alters the β-Lactam Susceptibility of Staphylococcus aureus. [PDF]
PLoS ONE, 2015 Toxin-antitoxin (TA) systems are genetic elements of prokaryotes which encode a stable toxin and an unstable antitoxin that can counteract toxicity. TA systems residing on plasmids are often involved in episomal maintenance whereas those on chromosomes ...

Oral Phageome as Potential Modulators of Periodontal Dysbiosis. A Systematic Review
Oral Diseases, EarlyView.ABSTRACT Introduction The oral phageome, comprising bacteriophages inhabiting the oral cavity, has been proposed as a potential modulator of periodontal health and disease. This systematic review synthesizes current evidence on interactions between bacteriophages, key periodontal bacteria, and the host in periodontitis.

Type I Toxin-Antitoxin Systems in Clostridia [PDF]
Toxins, 2019 Type I toxin-antitoxin (TA) modules are abundant in both bacterial plasmids and chromosomes and usually encode a small hydrophobic toxic protein and an antisense RNA acting as an antitoxin. The RNA antitoxin neutralizes toxin mRNA by inhibiting its translation and/or promoting its degradation.
