ECOD is a hierarchical classification of protein domains according to their evolutionary relationships. This database contains our combined classification of structure predictions from 48 proteomes from AlphaFold Database with experimental structures from the Protein Data Bank. Previous versions of ECOD that solely classified the PDB are available here. Addtionally, published classifications of human, Vibrio parahaemolyticus, Salmonella enterica typhi and the original 48 proteomes are available.
