Lipoxygenases ({EC number|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: Lipoxygenases are found in plants, animals and fungi. Products of lipoxygenases are involved in diverse cell func...
