Hydroperoxide dehydratase.
based on mapping to UniProt Q40778
(9Z,11E,15Z)-(13S)-hydroperoxyoctadeca-9,11,15-trienoate = (9Z,15Z)- (13S)-12,13-epoxyoctadeca-9,11,15-trienoate + H(2)O.
-!- 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 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.
