catalytic mechanism is as follows: When the Rieske cluster is reduced, substrate binding induces several conformational changes that create room for oxygen binding. Dioxygen bound in a side-on fashion onto nonheme iron is activated by reduction to the peroxo state [Fe(III)-(hydro)peroxo]. This state may react directly with the bound substrate, or O-O bond cleavage may occur to generate Fe(V)-oxo-hydroxo species prior to the reaction. After producing a cisdihydrodiol, the product is released by reducing the nonheme iron |
