Bioinformatic exploration reveals features of tenpIN family of type III toxin-antitoxin systems in bacteria and viruses [PDF]
Scientific ReportsToxin-antitoxin (TA) systems in bacteria consist of two genes: one encoding a toxin that inhibits essential cellular processes and the other encoding an antitoxin that neutralizes the toxin under homeostatic conditions.

Free-Living Bacteria May Utilize Chromosomal Toxin–Antitoxin Systems to Mediate K Sensing and Control by Continuously Modulating the Ratio of Injury: Repair Throughout the Life Cycle [PDF]
ToxinsA recent publication proposed that the main biological function of chromosomal toxin–antitoxin systems (TASs) in free-living bacteria is to optimize fitness by mediating K Sensing and Control via a Nutrient-Responsive Cybernetic System.

Keeping the wolves at bay: antitoxins of prokaryotic type II toxin-antitoxin systems
Frontiers in Molecular Biosciences, 2016 In their initial stages of discovery, prokaryotic toxin-antitoxin (TA) systems were confined to bacterial plasmids where they function to mediate the maintenance and stability of usually low- to medium-copy number plasmids through the post-segregational ...
