Crystal Structure of the Escherichia coli Fic Toxin-Like Protein in Complex with Its Cognate Antitoxin [PDF]

open access: yes, 2016
FIC domain proteins mediate post-translational modifications of target proteins, which typically results in their inactivation. Depending on the conservation of crucial active site residues, the FIC fold serves as structural scaffold for various ...

The Association of the mazEF Toxin-antitoxin System and Vancomycin Resistance in Clinical Isolates of Vancomycin Resistant Enterococcus faecalis [PDF]

open access: yes, 2022
Vancomycin resistant enterococci are challenging bacteria as they are difficult to be eradicated. Toxin-antitoxin (TA) systems are genetic elements located in most prokaryotic genomes.

A toxin-deformation dependent inhibition mechanism in the T7SS toxin-antitoxin system of Gram-positive bacteria

open access: yesNature Communications, 2022
Toxin EsaD secreted by some S. aureus strains through the type VII secretion system (T7SS) specifically kills those strains lacking the antitoxin EsaG. Here we report the structures of EsaG, the nuclease domain of EsaD and their complex, which together ...

The Bacillus cereus spoIIS programmed cell death system

open access: yesFrontiers in Microbiology, 2015
Programmed cell death in bacteria is generally associated with two¬ component toxin antitoxin systems. The SpoIIS toxin-antitoxin system, consisting of a membrane bound SpoIISA toxin and a small, cytosolic antitoxin SpoIISB, was originally identified in ...

The vapB-vapC operon of Acidovorax citrulli functions as a bona-fide toxin-antitoxin module

open access: yesFrontiers in Microbiology, 2016
Toxin–antitoxin systems are commonly found on plasmids and chromosomes of bacteria and archaea. These systems appear as biscystronic genes encoding a stable toxin and a labile antitoxin, which protects the cells from the toxin’s activity. Under specific,

VapC Toxins from Mycobacterium tuberculosis are ribonucleases that differentially inhibit growth and are neutralized by cognate VapB antitoxins [PDF]

open access: yes, 2011
The chromosome of Mycobacterium tuberculosis (Mtb) encodes forty seven toxin-antitoxin modules belonging to the VapBC family. The role of these modules in the physiology of Mtb and the function(s) served by their expansion are unknown.

TasA-tasB, a new putative toxin-antitoxin (TA) system from Bacillus thuringiensis pGI1 plasmid is a widely distributed composite mazE-doc TA system

open access: yesBMC Genomics, 2006
Background Post-segregational killing systems are present in a large variety of microorganisms. When found on plasmids, they are described as addiction systems that act to maintain the plasmid during the partitioning of the cell.

Mycobacterium tuberculosis Rv0229c Shows Ribonuclease Activity and Reveals Its Corresponding Role as Toxin VapC51

open access: yesAntibiotics, 2023
The VapBC system, which belongs to the type II toxin–antitoxin (TA) system, is the most abundant and widely studied system in Mycobacterium tuberculosis.

RNA Regulated Toxin-Antitoxin Systems in Pathogenic Bacteria

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
The dynamic host environment presents a significant hurdle that pathogenic bacteria must overcome to survive and cause diseases. Consequently, these organisms have evolved molecular mechanisms to facilitate adaptation to environmental changes within the ...
