Arachidonate lipoxygenases
arachidonate lipoxygenases
Lipoxygenases ( EC 1.13.11.- ) are a family of iron -containing enzymes that catalyse the dioxygenation of polyunsaturated fatty acids in lipids containing a cis,cis-1,4- pentadiene structure. It catalyses the following reaction:   fatty acid + O 2 = fatty acid hydroperoxide   Lipoxygenases are found in plants, animals and fungi. Products of lipoxygenases are involved in diverse cell functions.
