About BioEmu Microsoft

BioEmu is a deep learning system developed by Microsoft Research AI for Science that emulates protein equilibrium ensembles by generating thousands of statistically independent structures per hour on a single GPU. It integrates over 200 milliseconds of molecular dynamics simulations, static structures, and experimental protein stabilities using novel training algorithms. BioEmu captures diverse functional motions such as cryptic pocket formation, local unfolding, and domain rearrangements, and predicts relative free energies with 1 kcal/mol accuracy compared to millisecond-scale MD and experimental data. By jointly modelling structural ensembles and thermodynamic properties, BioEmu provides mechanistic insights and amortizes the cost of MD and experimental data generation, offering a scalable path toward understanding and designing protein function.
