LIPOXYGENASE-3 (SOYBEAN) COMPLEX WITH 13(S)-HYDROPEROXY-9(Z),11(E)-OCTADECADIENOIC ACID

Overview

Polyunsaturated fatty acid metabolism is governed primarily by two, enzymes, prostaglandin H synthase and lipoxygenase. The crystal structure, of the metastable product-oxidized purple form of soybean lipoxygenase-3, was determined at 2.0 A resolution. The data reveal that the chromophore, corresponds to an iron-peroxide complex, a potential intermediate in the, catalyzed reaction. A significant alteration of the iron site accompanies, the formation of the complex. The structure, the first for a fatty, acid-lipoxygenase complex, also reveals an unexpected mode of binding, and, identifies amino acid residues that may play significant roles in, catalysis, regio- and stereoselectivity.
