Distribution of SSE content. The average distribution of SSE content is distinctive among different PPI types. More than 40% of atoms in interaction sites for all PPI types are positioned in non-regular regions. Interaction sites contain higher portion of non-regular regions than those of helix and strand regions. Especially, less than 20% of interaction sites are composed of strands.
