1.13.11.60 | additional information | the bifunctional enzyme forms (7S,8S)-7,8-dihydroxylinoleic acid from (8R)-hydroperoxylinoleic acid by intramolecular oxygen transfer. Linoleate diol synthases are fungal dioxygenase-cytochrome P450 fusion enzymes. P450 hydroxylases usually contain an acid-alcohol pair in the I-helices for the heterolytic scission of O2 and formation of compound I, i.e. Por+-Fe(IV)=O, and water. The function of the acid-alcohol pair appears to be replaced by a different amide residue, Asn938 of 7,8-LDS, for heterolysis of (8R,9Z,12Z)-8-hydroperoxyoctadeca-9,12-dienoate to generate compound I | Gaeumannomyces graminis | ? | - |
