WebDec 9, 2024 · When did Daniel Koshland propose the induced fit model? Daniel Koshland offered a solution to this puzzle in 1958. The induced-fit model is actually an offshoot of an earlier theory proposed by Emil Fischer in 1894, the lock-and-key model. The lock-and-key model states that the substrate acts as a ‘key’ to the ‘lock’ of the active site. WebNov 19, 2024 · Then, in 1958, Daniel Koshland modified the lock and key theory with the induced fit model, claiming that enzymes are partially flexible and that the active site of the enzyme will reshape to fit ...
