New York, John Wiley & Sons Inc,pp New York, John Wiley & Sons Inc,pp As for other enzymes in the LOX pathway, LTA 4 H is an ancient gene, highly conserved from C. elegans to humans, despite the lack of orthologs in the leech and acorn worm.

FLAP and leukotriene C 4 synthase (LTC 4 S) from the MAPEG superfamily are believed to have evolved only in vertebrates (Jakobsson et al. ).LTC 4 S may have originated from an ancestral gene in the basal Metazoa.

The production of [3 H]arachidonoyl/[35 S]cysteinyl leukotrienes C 4 and E 4 by islets was compared with that by mouse resident peritoneal macrophages and with the lipoxygenase metabolism of rabbit polymorphonuclear leukocytes. The stimulus-specific nature of leukotriene biosynthesis was characterized by low basal biosynthesis in unstimulated.

The lipoxygenases are related to each other based upon their similar genetic structure and dioxygenation activity.

However, one lipoxygenase, ALOXE3, while having a lipoxygenase genetic structure, possesses relatively little dioxygenation activity; rather its primary activity appears to be as an isomerase that catalyzes the conversion of hydroperoxy unsaturated fatty acids to their 1,5-epoxide.

Data synthesis: Leukotrienes are biologically active 5-lipoxygenase products of arachidonic acid metabolism that are involved in the mediation of various inflammatory disorders.

Of these, leukotriene B4 (a potent chemoattractant for leukocytes) and the sulfidopeptide leukotrienes C4, D4, and E4 (which increase vascular permeability and.

Recently, it has been shown that lipoxygenase (LO) products affect the substrate specificity of human LO. In the current paper, we demonstrate that soybean LO-1 (sLO-1) is not affected by its own products, however, inhibitors which bind the allosteric site, oleyl sulfate (OS) and palmitoleyl sulfate (PS), not only lower catalytic activity, but also change the substrate specificity, by.

Unlike 5-LO, whose downstream products include both the HETEs and leukotrienes, the effects of LO are primarily attributed to the production of HETE. Activation of LO has been shown to accelerate inflammation via p38 mitogen-activated protein kinase (p38 MAPK) and nuclear factor κB pathways, cause oxidation of low density lipoprotein.

The role of sulfidopeptide leukotrienes in asthma alone or in association with other mediators is still debated. Sulfidopeptide leukotrienes (s-LT) C4, D4 and E4 are 5-lipoxygenase derivatives of membrane arachidonic acid.

All s-LT contract bronchial smooth muscle. Leukotriene A(4) (LTA(4)) is a chemically reactive conjugated triene epoxide product derived from 5-lipoxygenase oxygenation of arachidonic acid.

At physiological pH, this reactive compound has a half-life of less than 3 s at 37 degrees C and approximately 40 s at 4 degrees C. Regardless of this aqu.

Leukotrienes are a family of eicosanoid inflammatory mediators produced in leukocytes by the oxidation of arachidonic acid (AA) and the essential fatty acid eicosapentaenoic acid (EPA) by the enzyme arachidonate 5-lipoxygenase.

Leukotrienes use lipid signaling to convey information to either the cell producing them (autocrine signaling) or neighboring cells (paracrine signaling) in order to.

An antileukotriene, also known as leukotriene modifier and leukotriene receptor antagonist, is a medication which functions as a leukotriene-related enzyme inhibitor (arachidonate 5-lipoxygenase) or leukotriene receptor antagonist (cysteinyl leukotriene receptors) and consequently opposes the function of these inflammatory mediators; leukotrienes are produced by the immune system and serve to.

We have recently demonstrated that rat colon can convert 14 Carachidonic acid into both lipoxygenase and cyclo-oxygenase products, and that this metabolism is stimulated by the laxative phenolphthalein (Capasso et al ).
