ENZYME

ENZYME entry: EC 4.2.1.92

Accepted Name
hydroperoxide dehydratase
Alternative Name(s)
allene oxide synthase
AOS
hydroperoxide isomerase
Reaction catalysed
(13S)-hydroperoxy-(9Z,11E,15Z)-octadecatrienoate <=> (9Z,13S,15Z)-12,13-epoxyoctadeca-9,11,15-trienoate + H2O
Comment(s)
  • 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.
