WebJan 2, 2024 · Antitoxins are either RNAs or proteins that inhibit toxicity at different levels: translation, activity or even stability of the toxin. Classification of toxin–antitoxin systems … WebToxin-antitoxin (TA) modules are ubiquitous in bacteria, but their biological importance in stress adaptation remains a matter of debate. The inactive ζ-ε2-ζ TA complex is composed of one labile ε2 antitoxin dimer flanked by two stable ζ toxin monomers. Free toxin ζ reduces the ATP and GTP levels, increases the (p)ppGpp and c-di-AMP pool, inactivates a fraction …
