Lipoxygenases (LOX) comprise a family of non-heme-iron-containing proteins that cata-lyze the dioxygenation of polyunsaturated fatty acids to form bioactive lipids. Metabolism of arachidonic acid by LOXs leads to the formation of regioisomeric cis/trans-conjugated hydroxyeicosatetraenoic acids (HeTes), leukot-rienes, lipoxins, and hepoxilins. Dependent on the predominant position of the incorpo...
