=== Biocatalytic and Chemoenzymatic Approaches for Chemical Synthesis ===
The application of the ene reduction can be observed in both biocatalytic and chemoenzymatic approaches for chemical synthesis. The capacity of ene reduction to catalyze diverse reactions with high selectivity renders it a valuable tool in the synthesis of complex and stereospecific compounds. Ene reduction plays a role in the production of fine chemicals, pharmaceutical compounds, agrochemicals, and biofuels. Highlighting the functionality of ene reductases emphasizes their crucial role in catalyzing a variety of reactions. One example is the ene-reductase Old-Yellow-Enzyme (OYE) which can reduce a carbon-carbon double bond (C=C) with a catalytic amount of NADH.<ref name=":3" />
