When bound to their toxin partners, they can bind DNA via the N-terminus and repress the expression of operons containing genes encoding the toxin and the antitoxin [2] ...Members of this family act as antitoxins in type II toxin-antitoxin systems [1]. When bound to their toxin partners, they can bind DNA via the N-terminus and repress the expression of operons containing genes encoding the toxin and the antitoxin [2]. This domain complexes with Txe toxins containing Pfam:PF06769, Fic/DOC toxins containing Pfam:PF02661 and YafO toxins containing Pfam:PF13957.
