A curated structural dataset of peptide–protein complexes reveals biases in existing datasets and principles of peptide binding

Protein Science, Volume 35, Issue 10, October 2026.
Abstract Peptide–protein interactions are fundamental to many biological processes, and peptide design is gaining interest due to its therapeutic potential. This has led to the emergence of various structural databases, such as PepBDB and Peptipedia, that classify peptides as polypeptides with fewer than 50 amino acids. These databases provide valuable
