Structural insights into chaperone addiction of toxin-antitoxin systems
SecB homologs can be associated with stress-responsive type II toxin–antitoxin (TA) systems and form tripartite toxin-antitoxin-chaperone systems (TAC).

Shaping Pulses to Control Bistable Monotone Systems Using Koopman Operator [PDF]
In this paper, we further develop a recently proposed control method to switch a bistable system between its steady states using temporal pulses. The motivation for using pulses comes from biomedical and biological applications (e.g.

Characterization of HicAB toxin-antitoxin module of Sinorhizobium meliloti
Background Toxin-antitoxin (TA) systems are little genetic units generally composed of two genes encoding antitoxin and toxin. These systems are known to be involved in many functions that can lead to growth arrest and cell death.

Evaluating the Potential for Cross-Interactions of Antitoxins in Type II TA Systems
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 ...

Bacterial type I toxin-antitoxin systems [PDF]
Toxin-antitoxin (TA) loci encode two-component systems that consist of a stable "toxin" whose ectopic overexpression either kills cells or confers growth stasis, and an unstable "antitoxin". TA systems have been initially discovered on plasmids, where they confer stability of maintenance through post-segregational killing (PSK). Plasmid loss results in

The bacterial antitoxin HipB establishes a ternary complex with operator DNA and phosphorylated toxin HipA to regulate bacterial persistence [PDF]
Nearly all bacteria exhibit a type of phenotypic growth described as persistence that is thought to underlie antibiotic tolerance and recalcitrant chronic infections.

Bacterial toxin-antitoxin systems targeting translation [PDF]
10 p.-2 fig. Toxin-antitoxin systems (TAS) emerged more than 25 years ago and have since developed as an important field in molecular microbiology. TAS are autoregulated operons coding a stable toxin and an unstable antitoxin found in the plasmids and chromosomes of Bacteria and Archaea.

Molecular processes underlying synergistic linuron mineralization in a triple-species bacterial consortium biofilm revealed by differential transcriptomics [PDF]
The proteobacteria Variovorax sp. WDL1, Comamonas testosteroni WDL7, and Hyphomicrobium sulfonivorans WDL6 compose a triple-species consortium that synergistically degrades and grows on the phenylurea herbicide linuron.

Toxin-Antitoxin Systems and Persistence
Toxin-antitoxin (TA) systems are small genetic modules comprising a stable toxic protein and an antitoxin preventing the toxin activity. In type II TA systems, antitoxins are unstable proteins that are degraded by host ATP-dependent proteases. In steady-state conditions, the antitoxin forms a complex with the toxin in which the toxic activity is ...
