Classic [https://en.wikipedia.org/wiki/Michaelis%E2%80%93Menten_kinetics Michaelis-Menten kinetics]were determined for each generation of the enzyme. As the Diels-Alderase relies on a catalyzed interaction between both the diene and dienophile, a Michaelis binding constant (''K<sub>m</sub>'' value) was determined for each substrate separately before catalytic efficiency was calculated. The CE20 model of the enzyme is over 300-fold more efficient than the first enzyme model due to increasing active site specificity [Fig. 4].<ref name="Preiswerk"/>
