Toxins, Targets, and Triggers: An Overview of Toxin-Antitoxin Biology

WebAug 26, 2009 · Toxin-antitoxin (TA) modules are gene pairs specifying for a toxin and its antitoxin and are found on the chromosomes of many bacteria including pathogens. Here we report how each of five such TA systems in E. coli affect bacterial cell death differently in liquid media and during biofilm formation. WebMar 6, 2014 · Toxin-antitoxin (TA) systems are small genetic modules originally discovered as plasmid-borne loci that promote plasmid maintenance in bacterial populations by killing daughter cells devoid of the TA encoding plasmid [ 1 ]. TA loci were subsequently identified in many bacterial and archeal chromosomes, thus suggesting alternative functions [ 2 ]. earbuds and ear ringing
