Browse and Explore ECOD Annotations
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.
