Expression, Purification, and Functional Analysis of Novel RelE Operon from X. nematophila

open access: yesThe Scientific World Journal, 2014
Bacterial toxin-antitoxin (TA) complexes induce programmed cell death and also function to relieve cell from stress by various response mechanisms. Escherichia coli RelB-RelE TA complex consists of a RelE toxin functionally counteracted by RelB antitoxin.

Shaping Pulses to Control Bistable Monotone Systems Using Koopman Operator [PDF]

open access: yes, 2016
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.

RHS-elements function as type II toxin-antitoxin modules that regulate intra-macrophage replication of Salmonella Typhimurium.

open access: yesPLoS Genetics, 2020
RHS elements are components of conserved toxin-delivery systems, wide-spread within the bacterial kingdom and some of the most positively selected genes known. However, very little is known about how Rhs toxins affect bacterial biology.

Geometric Properties of Isostables and Basins of Attraction of Monotone Systems [PDF]

open access: yes, 2017
In this paper, we study geometric properties of basins of attraction of monotone systems. Our results are based on a combination of monotone systems theory and spectral operator theory.

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

open access: yesToxins, 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 ...

Bacterial type I toxin-antitoxin systems [PDF]

open access: yesRNA Biology, 2012
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

Release of vasopressin from isolated permeabilized neurosecretory nerve terminals is blocked by the light chain of botulinum A toxin [PDF]

open access: yes, 1990
The intracellular action on exocytosis of botulinim A toxin and constituent chains was studied using permeabilized isolated nerve endings from the rat neural lobe. The release of the neuropeptide vasopressin was measured by radioimmunoassay.

Viral evasion of a bacterial suicide system by RNA-based molecular mimicry enables infectious altruism.

open access: yesPLoS Genetics, 2012
Abortive infection, during which an infected bacterial cell commits altruistic suicide to destroy the replicating bacteriophage and protect the clonal population, can be mediated by toxin-antitoxin systems such as the Type III protein-RNA toxin-antitoxin

Bacterial toxin-antitoxin systems targeting translation [PDF]

open access: yesJournal of Applied Biomedicine, 2010
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.

AAU-Specific RNA Cleavage Mediated by MazF Toxin Endoribonuclease Conserved in Nitrosomonas europaea

open access: yesToxins, 2016
Nitrosomonas europaea carries numerous toxin-antitoxin systems. However, despite the abundant representation in its chromosome, studies have not surveyed the underlying molecular functions in detail, and their biological roles remain enigmatic.
