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

Pharmacokinetics of Human Recombinant Anti-Botulinum Toxin Antibodies in Rats

open access: yesToxins, 2019
Botulinum neurotoxins (BoNT) are potential biothreat agents due to their high lethality, potency, and ease of distribution, thus the development of antitoxins is a high priority to the US government.

Three dimensional structure of the MqsR:MqsA complex: a novel TA pair comprised of a toxin homologous to RelE and an antitoxin with unique properties. [PDF]

open access: yesPLoS Pathogens, 2009
One mechanism by which bacteria survive environmental stress is through the formation of bacterial persisters, a sub-population of genetically identical quiescent cells that exhibit multidrug tolerance and are highly enriched in bacterial toxins ...

Metabolic Promiscuity of an Orphan Small Alarmone Hydrolase Facilitates Bacterial Environmental Adaptation

open access: yesmBio, 2022
Small alarmone hydrolases (SAHs) are alarmone metabolizing enzymes found in both metazoans and bacteria. In metazoans, the SAH homolog Mesh1 is reported to function in cofactor metabolism by hydrolyzing NADPH to NADH.

Evolution of the SpoIISABC Toxin-Antitoxin-Antitoxin System in Bacilli

open access: yesToxins, 2016
Programmed cell death in bacteria is generally associated with two-component toxin-antitoxin systems. The SpoIISABC system, originally identified in Bacillus subtilis, consists of three components: a SpoIISA toxin and the SpoIISB and SpoIISC antitoxins ...

Toxin-Antitoxin Systems as Multilevel Interaction Systems

open access: yesToxins, 2014
Toxin-antitoxin (TA) systems are small genetic modules usually composed of a toxin and an antitoxin counteracting the activity of the toxic protein. These systems are widely spread in bacterial and archaeal genomes.

One cannot rule them all: Are bacterial toxins-antitoxins druggable?

open access: yesFEMS Microbiology Reviews, 2015
Type II (proteic) toxin–antitoxin (TA) operons are widely spread in bacteria and archaea. They are organized as operons in which, usually, the antitoxin gene precedes the cognate toxin gene.

Bacterial Toxin-Antitoxin Systems’ Cross-Interactions—Implications for Practical Use in Medicine and Biotechnology

open access: yesToxins, 2023
Toxin-antitoxin (TA) systems are widely present in bacterial genomes. They consist of stable toxins and unstable antitoxins that are classified into distinct groups based on their structure and biological activity. TA systems are mostly related to mobile

Toxin-Antitoxin Systems of Staphylococcus aureus

open access: yesToxins, 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.
