Some bacterial toxin-antitoxin systems consist of a labile antitoxin that inhibits a toxin, and a chaperone that stabilizes the antitoxin. Here, Bordes et al. identify a sequence within the antitoxin to which the chaperone binds and which can be transferred to other proteins to make them chaperone-dependent.
