Plant Lipoxygenases. Physiological and Molecular Features

Lipoxygenases (LOXs; EC[1.13.11.12][1]) are nonheme iron-containing dioxygenases widely distributed in plants and animals. LOX catalyzes the addition of molecular oxygen to polyunsaturated fatty acids containing a ( Z , Z )-1,4-pentadiene system to produce an unsaturated fatty acid hydroperoxide.
