From: A PDB-wide, evolution-based assessment of protein-protein interfaces
Interface area distribution of three datasets of interfaces. The interface areas for crystal contacts (red) and biological interfaces (green) are shown for three interface datasets: DCBio/Xtal (left), Bio/XtalMany (center) and Ponstingl (right). The numbers in parentheses refer to the counts of bio and xtal interfaces in each dataset.
