The vapB-vapC operon of Acidovorax citrulli functions as a bona-fide toxin-antitoxin module

open access: yesFrontiers 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,

A novel type I toxin-antitoxin system modulates persister cell formation in Staphylococcus aureus

open access: yesInternational 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 ...

TASmania: A bacterial Toxin-Antitoxin Systems database [PDF]

open access: yesPLOS 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.

Escherichia coli EHEC Germany outbreak preliminary functional annotation using BG7 system [PDF]

open access: yes, 2011
We have annotated the European outbreak E. coli EHEC genome sequenced by BGI (6-2-2011) and assembled with MIRA by Nick Loman (6-2-2011 ). Our system BG7, Bacterial Genome annotation of Era7 Bioinformatics, predicts ORFs and annotates them based on ...

TasA-tasB, a new putative toxin-antitoxin (TA) system from Bacillus thuringiensis pGI1 plasmid is a widely distributed composite mazE-doc TA system

open access: yesBMC Genomics, 2006
Background Post-segregational killing systems are present in a large variety of microorganisms. When found on plasmids, they are described as addiction systems that act to maintain the plasmid during the partitioning of the cell.

The role of small proteins in Burkholderia cenocepacia J2315 biofilm formation, persistence and intracellular growth [PDF]

open access: yes, 2019
Burkholderia cenocepacia infections are difficult to treat due to resistance, biofilm formation and persistence. B. cenocepacia strain J2315 has a large multi-replicon genome (8.06 Mb) and the function of a large fraction of (conserved) hypothetical ...

Functional Characterization of the mazEF Toxin-Antitoxin System in the Pathogenic Bacterium Agrobacterium tumefaciens

open access: yesMicroorganisms, 2021
Agrobacterium tumefaciens is a pathogen of various plants which transfers its own DNA (T-DNA) to the host plants. It is used for producing genetically modified plants with this ability.

YoeB toxin is activated during thermal stress. [PDF]

open access: yes, 2015
Type II toxin-antitoxin (TA) modules are thought to mediate stress-responses by temporarily suppressing protein synthesis while cells redirect transcription to adapt to environmental change.

Prevalence of Fst-like toxin–antitoxin systems [PDF]

open access: yesMicrobiology, 2010
Toxin–antitoxin (TA) systems are widespread in Gram-negative bacteria, and all systems identified to date encode a toxic protein and an unstable antitoxin, which may be in the form of either an antisense RNA (type I) or a second protein (type II). The enterococcal plasmid pAD1-encoded TA system (par), encoding the Fst toxin, was the first type I TA ...
