OpenFold Training Data

alphafold life sciences msa open source software openfold protein protein folding protein template


Multiple sequence alignments (MSAs) and template hits for 132,000 unique Protein Data Bank (PDB) chains, covering 640,000 PDB chains in total, and 270,000 filtered UniClust30 clusters. MSAs were generated with HHBlits (-n3) and JackHMMER against MGnify, BFD, UniRef90, and UniClust30 while templates were identified from PDB70 with HHSearch, all according to procedures outlined in the supplement to the AlphaFold 2 Nature paper, Jumper et al. 2021. We expect the database to be broadly useful to structural biologists training or validating deep learning models for protein structure prediction and related tasks.
