The effect of Staphylococcus aureus carriage in late pregnancy on antibody levels to staphylococcal toxins in cord blood and breast milk. [PDF]
, 2008 We investigated the effect of carriage of Staphylococcus aureus in the later stages of pregnancy on levels of antibody specific to the S. aureus toxins, staphylococcal enterotoxin B (SEB), staphylococcal enterotoxin C (SEC) and toxic shock syndrome toxin-

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 ...

Bacterial type I toxin-antitoxin systems [PDF]
RNA 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

PLoS 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

PLoS 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.

Variation at the capsule locus, cps, of mistyped and non-typable Streptococcus pneumoniae isolates [PDF]
, 2012 The capsule polysaccharide locus (cps) is the site of the capsule biosynthesis gene cluster in encapsulated Streptococcus pneumoniae. A set of pneumococcal samples and non-pneumococcal streptococci from Denmark, the Gambia, the Netherlands, Thailand, the

Bacterial toxin-antitoxin systems targeting translation [PDF]
Journal 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
Toxins, 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.

The bacterial antitoxin HipB establishes a ternary complex with operator DNA and phosphorylated toxin HipA to regulate bacterial persistence [PDF]
, 2014 Nearly all bacteria exhibit a type of phenotypic growth described as persistence that is thought to underlie antibiotic tolerance and recalcitrant chronic infections.

Toxin-Antitoxin Systems and Persistence
, 2019 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 ...
