Higba toxin antitoxin

WebHigB-HigA is a bacterial toxin–antitoxin (TA) system in which the antitoxin HigA can mask the endoribonuclease activity of toxin HigB and repress the transcription of the TA operon by... WebIt is a small protein encoded by a gene in a bicistronic operon, and the antitoxin blocks the toxicity of the toxin by forming a complex with the toxin [61,62,63]. G. parasuis H78 contains several type II TA families, including RelBE, MazEF, and HigBA, the most abundant of which are the six putative higBA loci identified in G. parasuis H78.
