ECOD (Evolutionary Classification of Protein Domains) annotations have been mapped to PDB structures.ECOD (Evolutionary Classification of Protein Domains) annotations have been mapped to PDB structures.

The Evolutionary Classification Of protein Domains (ECOD) database classifies domains according to evolutionary relationships: (A) architecture, (X) possible homology, (H) homology, (T) topology, (F): Family.

Compared with other classification databases (e.g., SCOP, CATH) ECOD emphasizes distant evolutionary relationships.

These ECOD annotations have been mapped to PDB structures.

Explore ECOD classifications for a particular structure through the Annotations tab and the Sequence tab (Protein Feature View) for 7ad1, a trimeric spike protein of SARS-CoV-2).

Use the ECOD Browser at RCSB.org to find proteins with a particular classification.
