Toxin-antitoxin (TA) systems are important genetic modules composed by two elements: a toxin, that is always a protein, and an antitoxin, that can be a RNA or a protein and neutralizes the toxic effect of toxin. These ...

Much of the diversity of prokaryotic genomes is contributed by the tightly controlled recombination activity of transposons (Tns). The Tn3 family is argu-ably one of the most widespread transposon families. Members carry ...

Adherent-invasive Escherichia coli (AIEC) corresponds to an E. coli pathovar proposed as a possible agent trigger associated to Crohn's disease. It is characterized for its capacity to adhere and to invade epithelial cells, ...

Toxin-antitoxin (TA) systems contribute to plasmid stability by a mechanism that relies on the differential stabilities of the toxin and antitoxin proteins and leads to the killing of daughter bacteria that did not receive ...

Toxin-antitoxin (TA) proteic systems encode a toxin and an antitoxin that regulate the growth and death of bacterial cells under various stress conditions. The ParE protein is a toxin that inhibits DNA gyrase activity and ...
