Toxin-Antitoxin ( TA ) systems are genetic elements that can be found in the genomes of nearly all bacteria.
They encode for a toxin protein as well as its cognate antitoxin.
When the antitoxin is degraded, the toxin is released and the host bacterium dies.
www.mpg.deToxin-Antitoxin-Systeme ( TA-Systeme ) sind DNA-Elemente, die im Genom fast aller Bakterien zu finden sind.
Sie kodieren für ein toxisches Protein und das entsprechende Antitoxin.
Wird letzteres abgebaut, kommt es zur Freisetzung des Toxins und der damit verbundenen Vergiftung der Zelle.
