ECOD: An Evolutionary Classification of Protein Domains
Figure 9
Venn diagram of the shared homologous domain pairs among those ECOD (cyan), SCOP (green), and CATH (red) nonredundant domains with similar (80%) domain ranges.
A plurality of domain pairs are shared among all three classifications. A large fraction of domain pairs can solely be observed in ECOD. 11.4% of domain pairs are only shared between ECOD and CATH.
