AlphaFold Protein Structure Database
AlphaFold DB, EMBL-EBI and Google DeepMind's database of over 260 million predicted protein structures, through its keyless API at alphafold.ebi.ac.uk: the predicted structure of a protein with its pLDDT confidence, the residue ranges that are confident and those likely disordered, and links to the model, PAE and confidence files; predicted complexes containing a protein with their partners and interface scores (ipTM, ipSAE, pDockQ); and AlphaMissense pathogenicity predictions for every possible missense substitution in a human protein. Takes UniProt accessions, entry names, AlphaFold model IDs, entry URLs or gene symbols. Data is CC BY 4.0: every result carries its licence, citations and entry page.
