Linoleate 10R-lipoxygenase

Linoleate 10R-lipoxygenase (EC 1.13.11.62, 10R-DOX, (10R)-dioxygenase, 10R-dioxygenase) is an enzyme with systematic name linoleate:oxygen (10R)-oxidoreductase.^[1]^[2] This enzyme catalyses the following chemical reaction

linoleate + O₂

\rightleftharpoons

(8E,10R,12Z)-10-hydroperoxy-8,12-octadecadienoate

Linoleate 10R-lipoxygenase is involved in biosynthesis of oxylipins.
