WebInterestingly, the full-length hicA gene is not toxic in F. nucleatum, but a truncated hicA gene version lacking the first six amino acids is functional as a toxin. The toxin expression is driven by an rpsJ promoter and is controlled at its translational level by using a theophylline-responsive riboswitch unit. WebJun 11, 2024 · Abstract After the first discovery in the 1980s in F-plasmids as a plasmid maintenance system, a myriad of toxin-antitoxin (TA) systems has been identified in bacterial chromosomes and mobile genetic elements (MGEs), including plasmids and bacteriophages.
