molecular dynamics simulations. The enzyme is stable in both apo and substrate bound complex forms. The substrate adopts a bent structure inside the enzyme active site, with the C1 carboxylate and C20 methyl groups of the substrate at two terminal ends of the two sides, while the substrate is folded at the double allylic carbon center (C10 position)
