WebKoshland's induced fit theory Induced fit theory was pro-posed by Koshland. Proteins are not rigid. The substrate induces the enzyme to adjust its shape leading to the formation of enzyme sub-strate complex. Then, the enzyme acts on substrate and forms products. Many enzymes function in this way.
