9,12-octadecadienoate 8-hydroperoxide 8R-isomerase (EC 5.4.4.5, 5,8-LDS (bifunctional enzyme), 5,8-linoleate diol synthase (bifunctional enzyme), 8-hydroperoxide isomerase, (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate mutase ((5S,8R,9Z,12Z)-5,8-dihydroxy-9,12-octadecadienoate-forming), PpoA) is an enzyme with systematic name (8R,9Z,12Z)-8-hydroperoxyoctadeca-9,12-dienoate hydroxymutase ((5S,8R,9Z,12Z)-5,8-dihydroxyoctadeca-9,12-dienoate-forming).[1][2][3] This enzyme catalyses the following chemical reaction

(8R,9Z,12Z)-8-hydroperoxyoctadeca-9,12-dienoate [math]\displaystyle{ \rightleftharpoons }[/math] (5S,8R,9Z,12Z)-5,8-dihydroxyoctadeca-9,12-dienoate

This enzyme contains heme.
