The role of a toxin-antitoxin system in the arms race between bacteria and phage
… restriction modification and CRISPR-Cas systems. These defense mechanisms, in turn, have influenced the emergence of phage anti-defense systems, highlighting the intense, ongoing evolutionary arms race between phages and their bacterial hosts. Toxin-antitoxin (TA) systems are widespread …

High-Throughput Screening Development Using Photonic-Crystal Optical Biosensor
… that are DNA sequence-dependent (the bacterial toxin-antitoxin system MazEF), and those that are DNA sequence-independent (the human apoptosis inducing factor (AIF)). The PC technology was further utilized in a screen for inhibitors of the AIF-DNA interaction, and through this screen aurin …

Bacterial defense islands: CRISPR-Cas and toxin-antitoxin systems /
… developed a set of DNA and RNA-targeting systems to combat their invaders – bacteriophages. Fundamental research on these resistance mechanisms led to the discovery of molecular tools for genetic engineering, such as restriction enzymes, bacterial argonautes and CRISPR-Cas systems. …

Phenotypic variation in Photorhabdus temperata K122
… AstR-AstS two component signal transduction system. A putative DNA binding protein, Ner, has also been shown to influence the phenotypic switch when overexpressed. This study has confirmed the role of HexA in the regulation of symbiosis, virulence and phenotypic variation in P. temperata K122 …

Physiological response of Rhizobium leguminosarum during bacteroid development
… N2 fixation. Other findings include a putative toxin-antitoxin system that hinders N2 fixation when disturbed.

Investigation of the YefM-YoeBSa toxin-antitoxin systems as novel antibacterial targets
… of new antibacterial compounds. Bacterial toxin-antitoxin (TA) systems consist of a toxin capable of arresting cell growth and an antitoxin that binds to and inhibits the toxin under normal circumstances. Cellular stress causes a shift in the toxin/antitoxin ratio to favor the free toxin, …

Characterization of ToxINPa-sensitive bacteriophages of Serratia sp. ATCC 39006
… Abortive infection can be mediated by a Type III toxin-antitoxin system called ToxINPa, first found in Pectobacterium atrosepticum. ToxINPa consists of an endoribonuclease toxin and RNA antitoxin and is inactive as a heterohexameric complex until infection by certain phages causes destabilization …

Replication and stability of the linear plasmid pBSSB2
… proposed that the stability function acts as a toxin-antitoxin system, although the antitoxin has not yet been identified. A candidate promoter for a putative countertranscript and two potential ORFs as candidates for encoding the antitoxin have been suggested for future work to identify the …

Electrogenetic pathways in cyanobacteria
Living systems extract energy from the environment by coupling charge-transfer reactions between available electron donors and acceptors with the generation of electrochemical gradients across cellular membranes. The variety of strategies that organisms have evolved to harness the many …
