Koshlands theory of induced fit

WebAccording to the induced fit theory by Daniel Koshland, binding of substrate to the enzyme brings a conformational change in the enzyme to either enhance or inhibit its activity. The active site keeps changing its shape until it is bound to the substrate, the final binding gives a proper shape to the enzyme. Web16 mei 2024 · Active Site Binding Theories. There are two theories about how exactly an enzyme active site binds to substrates. These are the lock and key model and the induced fit model. The Lock and Key Model. The lock and key model of active site binding postulates that active sites possess the perfect shape to bind their substrates.
