Webb10 sep. 2024 · To characterize the nature of protein-protein interactions, three different models have been proposed. Emil Fischer first suggested the lock and key paradigm, which depicts inflexible interactions.Here, the shapes of the two interaction interfaces are complimentary, and binding induces relatively minimal conformational change. Webb(A) lock-key model, (B) induced-fit model, (C) selected-fit model and (D) keyhole-lock-key-model. Green key = binding substrate, red key = unbinding ligand. (For interpretation of …
