Induced fit describes a conformational change in a protein when it binds a ligand, in contrast to a lock-and-key model of ligand binding. A classical example of induced fit is binding of glucose to hexokinase, depicted in a morph between 3o8m and 3o80 below.

History of the concept
Induced fit was suggested by Koshland in 1958 [1], providing an alternative to the lock-and-key binding model that Emil Fischer proposed in 1899 [2].
