ID 1.13.11.60 DE linoleate 8R-lipoxygenase. AN 5,8-linoleate diol synthase (bifunctional enzyme). AN 7,8-linoleate diol synthase (bifunctional enzyme). CA (9Z,12Z)-octadecadienoate + O2 = (8R,9Z,12Z)-8-hydroperoxyoctadeca-9,12- CA dienoate. CC -!- The bifunctional enzyme from Aspergillus nidulans uses different heme CC domains to catalyze two separate reactions. CC -!- Linoleic acid is oxidized within the N-terminal heme peroxidase CC domain to (8R,9Z,12Z)-8-hydroperoxyoctadeca-9,12-dienoate, which is CC subsequently isomerized by the C-terminal P450 heme thiolate domain CC to (5S,8R,9Z,12Z)-5,8-dihydroxyoctadeca-9,12-dienoate (cf. CC EC 5.4.4.5). CC -!- The bifunctional enzyme from Gaeumannomyces graminis also catalyzes CC the oxidation of linoleic acid to (8R,9Z,12Z)-8-hydroperoxyoctadeca- CC 9,12-dienoate, but its second domain isomerizes it to (7S,8S,9Z,12Z)- CC 5,8-dihydroxyoctadeca-9,12-dienoate (cf. EC 5.4.4.6). CC -!- Formerly EC 1.13.11.44. DR Q9UUS2, LIDS_GAEGR ; G4N4J5, LIDS_PYRO7 ; B0Y6R2, PPOA_ASPFC ; DR Q4WPX2, PPOA_ASPFU ; Q6RET3, PPOA_EMEND ; G5EB19, PPOA_EMENI ; //
