WebAug 12, 2024 · In type I TA system, the antitoxin is an antisense RNA that arrests the translation of the toxin by binding to the toxin mRNA ( Gerdes and Wagner, 2007 ). In Type II TA system, antitoxin proteins neutralize toxins through direct protein-protein interactions ( Leplae et al., 2011 ). WebThe first type I toxin-antitoxin system to be found in gram-positive bacteria is the RNAI-RNAII system of the pAD1 plasmid in Enterococcus faecalis.
