Toxin antitoxin system
WebWhat are toxin-antitoxin systems? These toxic substances are part of toxin-antitoxin systems that are widely present in bacteria. They consist of a toxin which can affect a variety of cellular processes and an antitoxin that suppresses the toxin’s activity.

Here, we … WebJan 22, 2024 · Toxin–antitoxin (TA) systems are one of the conserved modules on conjugative plasmids. Here, we demonstrate the functional significance of a large group of antitoxins on conjugative plasmids: the antitoxin acts as an unexpected player in the negative control of plasmid replication.
WebApr 25, 2024 · Toxin-antitoxin systems (TAS) were originally known for their involvement in a process known as post-segregational killing (PSK), a plasmid maintenance mechanism based on the differential decay of the products of two plasmid-encoded genes: a toxin gene and its antagonistic antitoxin [ 1 – 3 ]. WebJul 26, 2024 · Antitoxins are unstable proteins or RNAs that counteract toxins. Based on the antitoxin nature and toxin-neutralization mechanism, TA systems can be divided into types I–VIII 6, 7.
