The reliable identification of \β-aggregating stretches in protein sequences is essential for the development of therapeutic agents for Alzheimer{\textquoteright}s and Parkinson{\textquoteright}s diseases, as well as other pathological conditions associated with protein deposition. Here, a model based on physicochemical properties and computational design of \β-aggregating peptide sequences is shown to be able to predict the aggregation rate over a large set of natural polypeptide sequences. Furthermore, the model identifies aggregation-prone fragments within proteins and predicts the parallel or anti-parallel \β-sheet organization in fibrils. The model recognizes different \β-aggregating segments in mammalian and nonmammalian prion proteins, providing insights into the species barrier for the transmission of the prion disease.
