a) Comparison of fine-grained structural coverage of subfamilies; subfamilies with a solved structure (black line), non-structural subfamilies within structural families (dark grey line), non-structural subfamilies within non-structural families (light grey line) Also shown in the comparative coarse-grained coverage of the largest non-structural families (thin grey line) b) Number of unique prokaryotic organisms represented in structurally uncharacterised families (Pfam-A) compared to the number found within structurally uncharacterised subfamilies within CATH and Pfam-A_struc families.
