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 …
WebThe TA system could be RNA or a protein, but in all TA systems reported to date, the antitoxin has been found to be unstable while the toxin is stable. 1 TA loci are often transferred by horizontal transformation and are more often associated with pathogenic bacteria; most of them have been found on plasmids containing antibiotic resistance, 2 ... WebFeb 13, 2024 · The toxin–antitoxin gene pairs have independent promoters and are transcribed either as an overlapping convergent (antitoxin is cis encoded antisense RNA; e.g., hok/Sok) or a non-overlapping divergent (antitoxin is trans encoded sRNA; e.g., tisB/istR-1 and dinQ/agrB in Escherichia coli) gene (Lee and Lee 2016).
