Protein-protein Interface Space (IMAGE) Georgia Institute of Technology Caption The foreground shows snapshots of structurally similar protein-protein interfaces (center), formed by proteins from different structural folds (corners). In the background are representations of the structural space of around 1,000 protein-protein interfaces. Each node represents a protein interface, and each edge represents significant structural similarity.
