WebMay 5, 2024 · Most bacterial genomes encode multiple autoregulatory 'poison-antidote' gene pairs called Toxin-Antitoxin systems (TAs)-encode a 'toxin' that inhibits metabolism and an 'antitoxin' that inhibits the activity of toxin protein. TAs are classified into several types of which Type II TAs are predominantly encoded by bacterial genomes and plasmids … WebSep 1, 2013 · Type I. Type I antitoxins are unstable antisense sRNAs. In most cases expression of the toxin is downregulated by base-pairing of the antitoxin sRNA with the stable mRNA of the toxin. 7 This interaction was shown to prevent binding to the ribosome and thereby arrests translation of the toxin mRNA. 8 An example for a type I TA system …
