BIOLOGICAL ACTIVITY

15-Lipoxygenase present in rabbit reticulocytes is presumed to be involved in the breakdown of mitochondrial membrane and the maturation of red cells (Ref. 0062). The enzyme is active with esterified polyunsaturated fatty acids contained in the membrane of subcelluar orgnelles or serum lipoprotein, and its peroxy products may be involved in the pathogenesis of arteriosclerosis (Ref. 0063).

METABOLISM

When arachidonic acid is allowed to react with 15-lipoxygenase, the predominant product is 15(S)-hydroperoxy-5,8,11,13-(Z,Z,Z,E)-eicosatetraenoic acid (Ref. 0061). The 15-hydroperoxy acid is further transformed to dihydroperoxy acids or 14,15-epoxy acid with a conjugated triene by the catalyses of 12- and 15-lipoxygenases (Ref. 0065), and is a precursor for lipoxin biosynthesis (Ref. 0035).

GENETIC INFORMATION

cDNA and genomic DNA of 15-lipoxygenases were cloned (Ref. 0064).
