Structures of a protein that were predicted by artificial intelligence (blue) and experimentally determined (green) match almost perfectly.
By Robert F. ServiceArtificial intelligence (AI) has solved one of biology’s grand challenges: predicting how proteins curl up from a linear chain of amino acids into 3D shapes that allow them to carry out life’s tasks.
Today, leading structural biologists and organizers of a biennial protein folding competition announced the achievement by researchers at DeepMind, a U.K.-based AI company.
