Results of the Protein Engineering Tournament: An Open Science Benchmark for Protein Modeling and Design.

The grand challenge of protein engineering is the development of computational models to characterize and generate protein sequences for arbitrary functions. Progress is limited by lack of (1) benchmarking opportunities, (2) large protein function datasets, and (3) access to experimental protein characterization. We introduce the Protein Engineering Tournament-a fully-remote competition designed to foster the development and evaluation of computational approaches in protein engineering. The tournament consists of a predictive round, predicting biophysical properties from protein sequences, followed by a generative round where novel protein sequences are designed, expressed, and characterized using automated methods. Upon completion, all datasets, experimental protocols, and methods are made publicly available. We detail the structure and outcomes of a pilot Tournament involving seven protein design teams, powered by six multi-objective datasets, with experimental characterization by our partner, International Flavors and Fragrances. Forthcoming Protein Engineering Tournaments aim to mobilize the scientific community towards transparent evaluation of progress in the field.
