This family carries several different examples of type II bacterial toxins of toxin-antitoxin systems including many HigB-like ones. The fold is referred to as the RelE/YoeB/Txe/Yeeu fold suggesting all examples of these are present in this family. Several plasmids with proteic killer gene-systems have been reported. All of them encode a stable toxin and an unstable antidote. Upon loss of the plasmid, the less stable inhibitor is inactivated more rapidly than the toxin, allowing the toxin to be activated. The activation of these systems results in cell filamentation and cessation of viable cell production. It has been verified that both the stable killer and the unstable inhibitor of the systems are short polypeptides. This family corresponds to the toxin [1,2].	Domain

This large family of DNA binding helix-turn helix proteins includes Cro Swiss:P03036 and CI Swiss:P03034. Within the protein Swiss:Q5F9C2, the full protein fold incorporates a helix-turn-helix motif, but the function of this member is unlikely to be that of a DNA-binding regulator, the function of most other members, so is not necessarily characteristic of the whole family [1].
