Catalysis in the Julia-Colonna epoxidation of alpha,beta-unsaturated ketones is due to binding of the hydroperoxide enolate intermediate by the three N-terminal amidic N-H groups of alpha-helical poly-leucine; the N-terminal pair forms an oxy-anion hole, whilst the third aids displacement of hydroxide.
