Biochem/physiol Actions

Alcohol dehydrogenase catalyzes the oxidative conversion of alcohol into aldehyde. It has a homodimeric structure with a co-enzyme binding domain at the C-terminal and an N-terminal catalytic domain. The active site is located at the interdomain cleft. Binding of NAD+ in the active site causes conformational changes which create the binding site for the alcohol substrate.
