TASmania: A bacterial Toxin-Antitoxin Systems database
PLOS Computational Biology, 2019 Bacterial Toxin-Antitoxin systems (TAS) are involved in key biological functions including plasmid maintenance, defense against phages, persistence and virulence. They are found in nearly all phyla and classified into 6 different types based on the mode of inactivation of the toxin, with the type II TAS being the best characterized so far.

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 ...

Characterisation of VapBC Toxin-Antitoxins from Mycobacterium tuberculosis [PDF]
, 2013 Toxin-antitoxin (TA) systems were identified more than 20 years ago on the mini F plasmid of Escherichia coli as plasmid stability elements; components responsible for purging bacterial cells that lack the plasmid from the population.

Identification, functional characterization, assembly and structure of ToxIN type III toxin antitoxin complex from E. coli [PDF]
, 2022 Toxin antitoxin TA systems are proposed to play crucial roles in bacterial growth under stress conditions such as phage infection. The type III TA systems consist of a protein toxin whose activity is inhibited by a noncoding RNA antitoxin. The toxin is

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 ...

The Biochemistry of VapBC Toxin-Antitoxins [PDF]
, 2011 The VapBC toxin-antitoxin (TA) systems were first identified in 2005 and little is known about their contemporary biological function, despite the fact that VapBC TAs are the largest TA family and are widespread in bacteria and archaea (Arcus, Rainey ...

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

Time to Diagnosis and Persistence: The Two Major Determinants of Effective Tuberculosis Control [PDF]
, 2015 The greatest challenge confronting effective tuberculosis (TB) eradication is the time to diagnosis, and duration of treatment of chronically infected individuals which represent a pool of infection.
