ID 5.4.4.6 DE 9,12-octadecadienoate 8-hydroperoxide 8S-isomerase. AN (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate mutase ((7S,8S,9Z,12Z)- AN 5,8-dihydroxy-9,12-octadecadienoate-forming). CA (8R,9Z,12Z)-8-hydroperoxyoctadeca-9,12-dienoate = (7S,8S,9Z,12Z)-7,8- CA dihydroxyoctadeca-9,12-dienoate. CC -!- The bifunctional enzyme from Gaeumannomyces graminis catalyzes the CC oxidation of linoleic acid to (8R,9Z,12Z)-8-hydroperoxyoctadeca-9,12- CC dienoate (cf. EC 1.13.11.60), which is then isomerized to CC (7S,8S,9Z,12Z)-5,8-dihydroxyoctadeca-9,12-dienoate. CC -!- Formerly EC 1.13.11.44. DR Q9UUS2, LIDS_GAEGR ; G4N4J5, LIDS_PYRO7 ; //
