Enzyme Information

1.13.11.12

Linoleate 13S-lipoxygenase.

based on mapping to UniProt P08170

(1) Linoleate + O(2) = (9Z,11E,13S)-13-hydroperoxyoctadeca-9,11-dienoate. (2) Alpha-linolenate + O(2) = (9Z,11E,13S,15Z)-13-hydroperoxyoctadeca- 9,11,15-trienoate.

-!- 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.
