interaction between c-Jun and Sp1 may account for the functional regulation of 12(S)-lipoxygenase gene regulation. The direct and cooperative interaction between c-Jun and Sp1 induced by EGF or PMA activates the expression of the human 12(S)-lipoxygenase gene. Sp1 may serve at least in part as a carrier to bring c-Jun to the promoter, thus transactivating the transcriptional activity of the human 12(S)-lipoxygenase gene

12/15-LOX generates (5Z,8Z,10E,14Z)-(12S)-12-hydroperoxyicosa-5,8,10,14-tetraenoate and (5Z,8Z,11Z,13E)-(15S)-15-hydroperoxyicosa-5,8,11,13-tetraenoate, when arachidonic acid is the substrate, the enzyme produces small amounts of 15S-HETE and primarily 12S-HETE (ratio of 1:3). In case of linolenic acid as a substrate, 13S-hydroxyoctadecadienoic acid (13S-HODE) is generated via the interstage product 13S-hydroperoxyoctadecadienoic acid (13SHPODE). Inflammatory eicosanoids are produced by eosinophils in a 12/15-LOX dependent manner. Another family of 12/15-LOX products are hepoxilins. They are enzymatic products of the conversion of 12S-HPETE, but can also be produced by non-enzymatic modification of 12S-HPETE or 12RHPETE. In the latter case, hemine or haemoglobin may act as a non-specific catalyst

the enzymatic peroxidation reaction consists of four consecutive steps: At first a hydrogen atom is stereoselectively abstracted from one of the bisallylic methylene-groups forming an enzyme-bound radical. Secondly one of the two associated cis-double bonds is rearranged and forms a conjugated cis-trans-diene. Consecutively a peroxy radical is produced by inserting molecular oxygen. Finally the radical is reduced by antarafacial re-inserting of a hydrogen atom. The resulting product of this peroxidation reaction depends on the respective fatty acid, which is used as a substrate
