Toxin Inactivation in Toxin/Antitoxin Systems
, 2019 Toxin/antitoxin (TA) systems are used primarily to inhibit phage, reduce metabolic activity during stress, and maintain genetic elements. Given the extreme toxicity of some of the toxins of these TA systems, we were curious how the cell silences toxins, if the antitoxin is inactivated or when toxins are obtained without antitoxins via horizontal gene ...

Comparative genomic analysis of Acinetobacter spp. plasmids originating from clinical settings and environmental habitats [PDF]
, 2018 Bacteria belonging to the genus Acinetobacter have become of clinical importance over the last decade due to the development of a multi-resistant phenotype and their ability to survive under multiple environmental conditions.

Bioinformatics and Functional Assessment of Toxin-Antitoxin Systems in Staphylococcus aureus
Toxins, 2018 Staphylococcus aureus is a nosocomial pathogen that can cause chronic to persistent infections. Among different mediators of pathogenesis, toxin-antitoxin (TA) systems are emerging as the most prominent.

A bacterial toxin-antitoxin module is the origin of inter-bacterial and inter-kingdom effectors of Bartonella. [PDF]
, 2017 Host-targeting type IV secretion systems (T4SS) evolved from conjugative T4SS machineries that mediate interbacterial plasmid transfer. However, the origins of effectors secreted by these virulence devices have remained largely elusive.

Caracterização da interação HipAB na Shewanella oneidensis MR1 [PDF]
, 2013 Mestrado em BioquímicaBacterial resistance is a major issue in research related to environmental and public health, due to the ineffectiveness of antibiotics, resulting from a subpopulation of bacterial cells entering a dormant state.

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

Excitable dynamics through toxin-induced mRNA cleavage in bacteria.
PLoS ONE, 2019 Toxin-antitoxin (TA) systems in bacteria and archaea are small genetic elements consisting of the genes coding for an intracellular toxin and an antitoxin that can neutralize this toxin. In various cases, the toxins cleave the mRNA.

The Role of Scientific Discovery in the Establishment of the First Biological Weapons Programmes [PDF]
, 2005 YesThis report addresses the scientific and technological discoveries in the biological sciences that enabled the early interest in biological warfare to move from hurling infected corpses into enemy cities in ancient times, through use of small cultures
