WebInduced fit- In 1959, Daniel E. Koshland suggested to the hypothesis. According to it, the active site does not possess any rigid lock-and-key conformations. The attachment of the substrate molecule to the enzyme molecule induces to modify the shape of the active site; hence, it becomes opposite to the substrate molecule. 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.
