Disulfide-rich peptides (DRPs) play many important physiological roles, and can be extremely taxonomically widespread. Here, Dash et al. show that a diverse centipede toxin family belongs to one of the most widespread DRP folds known, the cysteine-stabilized α/β fold, but that it represents a unique, ancient form of this fold.
