Binding substrates using an induced fit model

WebInduced Fit: According to the induced fit model, both enzyme and substrate undergo dynamic conformational changes upon binding. The enzyme contorts the substrate into its transition state, thereby increasing the rate of the reaction. Enzyme-Substrate Complex When an enzyme binds its substrate, it forms an enzyme-substrate complex. WebThe induced fit model allows for any substrate to bind with a specific enzyme regardless on the size whereas the lock and key model only allows a specific substrate. The induced-fit model allows for more flexibility whereas the lock and key model is more rigid. Previous question Next question

What is the correct model for enzyme-substrate complementarity?

WebMar 21, 2024 · The current theory, known as the induced-fit model, says that enzymes can undergo a change in conformation when they bind substrate molecules, and the active site has a shape complementary to that of the substrate only after the substrate is bound, as shown for hexokinase in Figure 3. After catalysis, the enzyme resumes its original structure. WebInduced Fit and Enzyme Function. For many years, scientists thought that enzyme-substrate binding took place in a simple “lock-and-key” fashion. This model asserted that the enzyme and substrate fit together perfectly in one instantaneous step. However, current research supports a more refined view called induced fit (). The induced-fit ...
