(a) Plot of mean residue dpx (dpxr, Å), (b) occluded surface packing value (OSP), and (c) residue solvent accessibility (rsa, %) versus residue number for the C-terminal bromodomain of human TAFII250 (PDB: 1EQF; residues 1500–1625). In the dpxr plot, important residues are labeled with their amino acid one-letter code and residue number; the same residues are labeled with an asterisk in the OSP and rsa plots. (d) Plot of mean residue dpx (dpxr, Å) versus OSP and rsa (%).
