Autoregulation of bacterial gene expression: lessons from the MazEF toxin-antitoxin system [PDF]
, 2019 Autoregulation is the direct modulation of gene expression by the product of the corresponding gene. Autoregulation of bacterial gene expression has been mostly studied at the transcriptional level, when a protein acts as the cognate transcriptional ...

MicroorganismsBacterial ubiquitous Toxin-Antitoxin (TA) systems are considered to be important survival mechanisms during stress conditions. In regular environmental conditions, the antitoxin blocks the toxin, whereas during imbalanced conditions, the antitoxin ...

Type II toxin/antitoxin system genes expression in persister cells of Klebsiella pneumoniae
, 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 ...

Toxin-Antitoxin Systems: Classification, Biological Function and Application in Biotechnology
, 2013 The toxin-antitoxin (TA) systems are systems in which an unstable antitoxin inhibits a stable toxin. This review aims to introduce the TA system and its biological application in bacteria. For this purpose, first we introduce a new classification for the

Phages carry orphan antitoxin-like enzymes to neutralize the DarTG1 toxin-antitoxin defense system [PDF]
The astounding number of anti-phage defenses encoded by bacteria is countered by an elaborate set of phage counter-defenses, though their evolutionary origins are often unknown. Here, we report the discovery of an orphan antitoxin counter-defense element
