Accepted Name
Linoleate 13S-lipoxygenase.
Alternative Name(s)
13-lipoperoxidase.
13-lipoxidase.
Carotene oxidase.
Lipoperoxidase.
Lipoxidase.
Reaction catalysed
  • Linoleate + O(2) <=> (9Z,11E,13S)-13-hydroperoxyoctadeca-9,11-dienoate
  • Alpha-linolenate + O(2) <=> (9Z,11E,13S,15Z)-13-hydroperoxyoctadeca-9,11,15-trienoate
Cofactor(s)
Fe cation.
Comment(s)
  • A common plant lipoxygenase that oxidizes linoleate and alpha- linolenate, the two most common polyunsaturated fatty acids in plants, by inserting molecular oxygen at the C(13) position with (S)- configuration.
  • This enzyme produces precursors for several important compounds, including the plant hormone jasmonic acid.
  • EC 1.13.11.58 catalyzes a similar reaction at the second available position of these fatty acids.
  • Formerly EC 1.13.1.13 and EC 1.99.2.1.
