Google DeepMind and Isomorphic Labs model that predicts 3D structures of proteins and their interactions with DNA, RNA and ligands.
AlphaFold 3 extends protein structure prediction to complexes of proteins, nucleic acids, small molecules and ions. Researchers can use it free through the AlphaFold Server web tool for non-commercial work, with a daily limit on predictions; model code and weights are available to academic users on request. Commercial drug-discovery use requires a licence through Isomorphic Labs.
