Product
(9Z,15Z)-(13S)-12,13-epoxyoctadeca-9,11,15-trienoate [CPD:C04672];
H2O [CPD:C00001]
Comment
Acts on a number of unsaturated fatty-acid hydroperoxides, forming the corresponding allene oxides. The product of the above reaction is unstable and is acted upon by EC 5.3.99.6, allene-oxide cyclase, to form the cyclopentenone derivative (15Z)-12-oxophyto-10,15-dienoate (OPDA), which is the first cyclic and biologically active metabolite in the jasmonate biosynthesis pathway [3]. The enzyme from many plants belongs to the CYP-74 family of P-450 monooxygenases [4].
