WebJun 7, 2024 · Bacterial toxin-antitoxin (TA) modules are abundant genetic elements that encode a toxin protein capable of inhibiting cell growth and an antitoxin that counteracts the toxin. The majority of toxins are enzymes that interfere with translation or DNA replication, but a wide variety of molecular activities and cellular targets have been described. Webtoxoid, bacterial poison ( toxin) that is no longer active but retains the property of combining with or stimulating the formation of antibodies. In many bacterial diseases, the bacteria remain sequestered in one part of the body but produce a poison (exotoxin) that causes the disease manifestations.
