Summary Introduction
Toxin-antitoxin (TA) module is a small genetic system that is comprised of a toxin gene and an antitoxin associated to it. The toxins present in the TA modules are all protein molecules, whereas the antitoxins are either proteins or RNAs that are non-coding. The toxin is more stable in nature when compared to antitoxin however antitoxin is highly expressed.
