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 ...

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.

HigB1 Toxin in Mycobacterium tuberculosis Is Upregulated During Stress and Required to Establish Infection in Guinea Pigs

open access: yesFrontiers in Microbiology, 2021
The extraordinary expansion of Toxin Antitoxin (TA) modules in the genome of Mycobacterium tuberculosis has received significant attention over the last few decades.

Multiple Toxin-Antitoxin Systems in Mycobacterium tuberculosis [PDF]

open access: yesToxins, 2014
The hallmark of Mycobacterium tuberculosis is its ability to persist for a long-term in host granulomas, in a non-replicating and drug-tolerant state, and later awaken to cause disease. To date, the cellular factors and the molecular mechanisms that mediate entry into the persistence phase are poorly understood. Remarkably, M.

Phage ϕC2 mediates transduction of Tn6215, encoding erythromycin resistance, between Clostridium difficile strains [PDF]

open access: yes, 2013
UNLABELLED: In this work, we show that Clostridium difficile phage ϕC2 transduces erm(B), which confers erythromycin resistance, from a donor to a recipient strain at a frequency of 10(-6) per PFU.

Dynamics-Based Regulatory Switches of Type II Antitoxins: Insights into New Antimicrobial Discovery

open access: yesAntibiotics, 2023
Type II toxin-antitoxin (TA) modules are prevalent in prokaryotes and are involved in cell maintenance and survival under harsh environmental conditions, including nutrient deficiency, antibiotic treatment, and human immune responses. Typically, the type

Hypothetical Functions of Toxin-Antitoxin Systems [PDF]

open access: yesJournal of Bacteriology, 2007
Toxin-antitoxin systems are very commonly found both on large, low-copy plasmids, where they increase effective stability ([35][1]), and on bacterial chromosomes, where their function has been the subject of considerable speculation.

Small Open Reading Frames, Non-Coding RNAs and Repetitive Elements in Bradyrhizobium japonicum USDA 110 [PDF]

open access: yes, 2016
Small open reading frames (sORFs) and genes for non-coding RNAs are poorly investigated components of most genomes. Our analysis of 1391 ORFs recently annotated in the soybean symbiont Bradyrhizobium japonicum USDA 110 revealed that 78% of them contain ...

Charged Amino Acids Contribute to ZorO Toxicity

open access: yesToxins, 2022
Chromosomally encoded toxin-antitoxin systems have been increasingly identified and characterized across bacterial species over the past two decades. Overproduction of the toxin gene results in cell growth stasis or death for the producing cell, but co ...

The mazEF toxin-antitoxin system as a novel antibacterial target in Acinetobacter baumannii [PDF]

open access: yes, 2014
Although analysis of toxin-antitoxin (TA) systems can be instructive, to date, there is no information on the prevalence and identity of TA systems based on a large panel of Acinetobacter baumannii clinical isolates.
