Bistability in type I toxin-antitoxin systems may lead to stress-induced persister formation

open access: yesnpj Systems Biology and Applications
Antibiotic persistence, characterized by a dormant subpopulation of bacterial cells that causes chronic and recurrent infections, remains poorly understood despite being recognized nearly a century ago. Toxin–antitoxin (TA) systems, which include a toxin

Toxin-antitoxin system [PDF]

open access: yes, 2018
Bakterije su razvile iznimnu sposobnost prilagodbe na različite životne uvjete. Uz pomoć raznih sustava i mehanizama daju brz stanični odgovor na stresore, tretman antibiotikom, stanje gladi i ostale nepovoljne uvjete. Jedan takav sustav pronađen je u

Higher-Order Structure in Bacterial VapBC Toxin-Antitoxin Complexes

open access: yes, 2017
Toxin-antitoxin systems are widespread in the bacterial kingdom, including in pathogenic species, where they allow rapid adaptation to changing environmental conditions through selective inhibition of key cellular processes, such as DNA replication or ...

A common origin for the bacterial toxin-antitoxin systems parD and ccd, suggested by analyses of toxin/target and toxin/antitoxin interactions.

open access: yesPLoS ONE, 2012
Bacterial toxin-antitoxin (TA) systems encode two proteins, a potent inhibitor of cell proliferation (toxin) and its specific antidote (antitoxin). Structural data has revealed striking similarities between the two model TA toxins CcdB, a DNA gyrase ...

Time to Diagnosis and Persistence: The Two Major Determinants of Effective Tuberculosis Control

open access: yes, 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.

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

open access: yes, 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 ...

The Biology and Biochemistry of PhoH2 proteins

open access: yes, 2013
PhoH2 proteins are found in a diverse range of organisms. To date little is known about these proteins and the role they play in the organisms in which they reside.

Identification and characterization of a toxin-antitoxin system in the pVir plasmid of Campylobacter jejuni

open access: yes, 2011
Toxin-antitoxin systems are prevalent in different bacterial organisms and are encoded in the chromosomal or plasmid DNA. The primary function of a plasmid toxin-antitoxin module is to stabilize the plasmid by eliminating plasmid-free daughter cells ...

Tuning the expression of the bacterial relBE toxin–antitoxin system in Saccharomyces cerevisiae allows characterizing the subsequent growth inhibition

open access: yes, 2023
International audienceThe bacterial toxin–antitoxin systems are each composed of a toxin, which severely inhibits bacterial cells growth, and a specific neutralizing antitoxin.
