From: A PDB-wide, evolution-based assessment of protein-protein interfaces

The Janin curve (1997) revisited. The Janin curve is plotted against EPPIC calls (based on evolutionary indicators, cyan, and on geometry, green) for all current (May 2014) PDB interfaces larger than 600 Å 2 and against all PDB interfaces conducive to infinite assemblies. The curves are plotted as normalized probability versus interface area.
