ECOD: An Evolutionary Classification of Protein Domains
Figure 8
A) Distribution of domains per chain for ECOD(red), SCOP(green), and CATH(blue).
Both ECOD and SCOP allow for multi-chain domains (MC), but these are a small fraction of the classification. ECOD contains slightly more single-chain domains than CATH, but less than SCOP. B) ECOD slightly favors smaller domains over SCOP and longer domains over CATH.
