From: Mapping small molecule binding data to structural domains
Power-law distribution of Pfam domains and small molecule ligands. (a-c) Log-log plots of observed distributions. X-Axis: proteome frequency of Pfam-A domains (a), ligands per Pfam domain (b), ligands per target (c). y-Axis: Number of instances with count X equal to corresponding x-value. (d-f) Corresponding cumulative distribution functions overlaid with the fit of the power-law distribution (dotted line). X-Axis: proteome frequency of Pfam-A domains (d), ligands per Pfam domain (e), ligands per target (f). Y-Axis: Proportion of instances with count X equal to or greater than x.
