Origin and Evolution of Protein Fold Designs Inferred from Phylogenomic Analysis of CATH Domain Structures in Proteomes
Figure 2
Distribution of CATH domain structures among taxonomical groups of domain distribution in superkingdoms.
The percentage of domain structures shared by superkingdoms was considered as coarse estimate of evolutionary conservation of the hierarchical levels of classification. CATH domain censuses were derived from the present study. SCOP values were taken directly from published data [16], [18] and involve 1030 Fs, 1740 FSF and 2,397 FF defined by SCOP v. 1.73.
