متن کاملPurification of arachidonate 5-lipoxygenase from porcine leukocytes and its reactivity with hydroperoxyeicosatetraenoic acids.
Arachidonate 5-lipoxygenase was purified to near homogeneity from the 105,000 X g supernatant of porcine leukocyte homogenate by immunoaffinity chromatography using a monoclonal anti-5-lipoxygenase antibody. Reaction of the purified enzyme with arachidonic acid produced predominantly 5-hydroperoxy-6,8,11,14-eicosatetraenoic acid with concomitant formation of several more polar compounds in smal...
متن کاملImmunocytochemical localization of arachidonate 15-lipoxygenase in erythrocytes, leukocytes, and airway cells.
In reticulocytes, the enzyme 15-lipoxygenase (15-LO) is believed to contribute to cellular differentiation, and in leukocytes and airway cells 15-LO generates inflammatory mediators. The recent availability of antibodies to 15-LO now allows us to determine which specific cells contain the enzyme, to characterize its subcellular localization, and to determine its expression at the translational ...
متن کاملStructure conservation in lipoxygenases: structural analysis of soybean lipoxygenase-1 and modeling of human lipoxygenases.
Lipoxygenases are a class of non-heme iron dioxygenases which catalyze the hydroperoxidation of fatty acids for the biosynthesis of leukotrienes and lipoxins. The structure of the 839-residue soybean lipoxygenase-1 was used as a template to model human 5-, 12-, and 15-lipoxygenases. A distance-based algorithm for placing side chains in a low homology environment (only the four iron ligands were...
