ECOD: An Evolutionary Classification of Protein Domains
Figure 4
Classification of ECOD and ECOD hierarchical levels with respect to the PDB and other classifications.
A) A cumulative sum of PDB release dates from Jan-2000 to Jan-2014 (red) compared to classified PDB depositions in ECOD (green), SCOP (cyan), and CATH (blue). Any deposition with at least one domain classified is counted. ECOD consistently classifies more structures than SCOP and CATH and is more up-to-date. b) The cumulative sum of PDB deposition dates in ECOD hierarchical levels. Each group is classified once by its oldest deposition. The number of new levels increases consistently over time over the 2000 to 2014 time period.
