Enzyme Information

1.13.11.58

Linoleate 9S-lipoxygenase.

based on mapping to UniProt P09186

Linoleate + O(2) = (9S,10E,12Z)-9-hydroperoxy-10,12-octadecadienoate.

-!- 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(9) position with (S)- configuration. -!- The enzyme plays a physiological role during the early stages of seedling growth. -!- The enzyme from Arabidopsis thaliana shows comparable activity toward linoleate and linolenate. -!- EC 1.13.11.12 catalyzes a similar reaction at another position of these fatty acids.
