Keeping the wolves at bay: antitoxins of prokaryotic type II toxin-antitoxin systems [PDF]
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 ...

Evaluating the Potential for Cross-Interactions of Antitoxins in Type II TA Systems
Toxins, 2020 The diversity of Type-II toxin–antitoxin (TA) systems in bacterial genomes requires tightly controlled interaction specificity to ensure protection of the cell, and potentially to limit cross-talk between toxin–antitoxin pairs of the same family of TA ...

Passive Immunisation in the Treatment of Infectious Diseases Related to Highly Potent Bacterial Toxins [PDF]
BiomedicinesThe discovery of microbial toxins as the primary factors responsible for disease manifestations and the discovery that these toxins could be neutralised by antitoxins are linked to the birth of immunology. In the late 19th century, the serum or plasma of

sRNA Antitoxins: More than One Way to Repress a Toxin
Toxins, 2014 Bacterial toxin-antitoxin loci consist of two genes: one encodes a potentially toxic protein, and the second, an antitoxin to repress its function or expression. The antitoxin can either be an RNA or a protein.

Toxinome—the bacterial protein toxin database [PDF]
mBioProtein toxins are key molecular weapons in biology that are used to attack neighboring cells. Bacteria use protein toxins to kill or inhibit the growth of prokaryotic and eukaryotic cells using various modes of action that target essential cellular ...

Novel type II toxin-antitoxin systems with VapD-like proteins [PDF]
mBioType II toxin-antitoxin (TA) systems are widespread in prokaryotes. They consist of neighboring genes encoding two small proteins: a toxin that inhibits a critical cellular process and an antitoxin that binds to and neutralizes the toxin.

Development of an Innovative in Vitro Potency Assay for Anti-Botulinum Antitoxins
Toxins, 2016 Botulinum neurotoxins are bacterial proteins that cause botulism, a life-threatening disease. Therapy relies mostly on post-intoxication antibody treatment. The only accepted method to measure the potency of, and to approve, antitoxin preparations is the

Toxin-Antitoxin Systems of Staphylococcus aureus
Toxins, 2016 Toxin-antitoxin (TA) systems are small genetic elements found in the majority of prokaryotes. They encode toxin proteins that interfere with vital cellular functions and are counteracted by antitoxins.

Dynamics-Based Regulatory Switches of Type II Antitoxins: Insights into New Antimicrobial Discovery [PDF]
Antibiotics, 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

Comprehensive comparative-genomic analysis of Type 2 toxin-antitoxin systems and related mobile stress response systems in prokaryotes [PDF]
Biology Direct, 2009 Background The prokaryotic toxin-antitoxin systems (TAS, also referred to as TA loci) are widespread, mobile two-gene modules that can be viewed as selfish genetic elements because they evolved mechanisms to become addictive for replicons and cells in ...
