mBio, 2019 Toxin-antitoxin (TA) systems are broadly distributed modules whose biological roles remain mostly unknown. The mqsRA system is a noncanonical TA system in which the toxin and antitoxins genes are organized in operon but with the particularity that the ...

The Bacillus cereus spoIIS programmed cell death system
Frontiers in Microbiology, 2015 Programmed cell death in bacteria is generally associated with two¬ component toxin antitoxin systems. The SpoIIS toxin-antitoxin system, consisting of a membrane bound SpoIISA toxin and a small, cytosolic antitoxin SpoIISB, was originally identified in ...

The vapB-vapC operon of Acidovorax citrulli functions as a bona-fide toxin-antitoxin module
Frontiers in Microbiology, 2016 Toxin–antitoxin systems are commonly found on plasmids and chromosomes of bacteria and archaea. These systems appear as biscystronic genes encoding a stable toxin and a labile antitoxin, which protects the cells from the toxin’s activity. Under specific,

An oxygen-sensitive toxin–antitoxin system
Nature Communications, 2016 Classical toxin–antitoxin systems in bacteria are based on silencing of a toxin by an antitoxin that, when inactivated, releases the toxin, resulting in a change in metabolism. Here, the authors characterize an oxygen-sensitive toxin–antitoxin system and

A novel type I toxin-antitoxin system modulates persister cell formation in Staphylococcus aureus
International Journal of Medical Microbiology, 2020 A plethora of toxin-antitoxin systems exist in bacteria and has multilateral roles in bacterial pathogenesis and virulence. Toxin-antitoxin systems have been involved in persister cell formation in Escherichia coli and Mycobacterium but have not been ...

RNA Regulated Toxin-Antitoxin Systems in Pathogenic Bacteria
Frontiers in Cellular and Infection Microbiology, 2021 The dynamic host environment presents a significant hurdle that pathogenic bacteria must overcome to survive and cause diseases. Consequently, these organisms have evolved molecular mechanisms to facilitate adaptation to environmental changes within the ...

Dynamics-Based Regulatory Switches of Type II Antitoxins: Insights into New Antimicrobial Discovery
Antibiotics, 2023 Type II toxin-antitoxin (TA) modules are prevalent in prokaryotes and are involved in cell maintenance and survival under harsh environmental conditions, including nutrient deficiency, antibiotic treatment, and human immune responses. Typically, the type
