Catalyzes the oxygenation of arachidonate ((5Z,8Z,11Z,14Z)-eicosatetraenoate) to 5-hydroperoxyeicosatetraenoate (5-HPETE) followed by the dehydration to 5,6- epoxyeicosatetraenoate (Leukotriene A4/LTA4), the first two steps in the biosynthesis of leukotrienes, which are potent mediators of inflammation (PubMed:19022417, PubMed:21233389, PubMed:22516296, PubMed:23246375, PubMed:24282679, PubMed:24893149, PubMed:31664810, PubMed:8615788, PubMed:8631361). Also catalyzes the oxygenation of arachidonate into 8-hydroperoxyicosatetraenoate (8-HPETE) and 12-hydroperoxyicosatetraenoate (12-HPETE) (PubMed:23246375). Displays lipoxin synthase activity being able to convert (15S)-HETE into a conjugate tetraene (PubMed:31664810). Although arachidonate is the preferred substrate, this enzyme can also metabolize oxidized fatty acids derived from arachidonate such as (15S)-HETE, eicosapentaenoate (EPA) such as (18R)- and (18S)-HEPE or docosahexaenoate (DHA) which lead to the formation of specialized pro-resolving mediators (SPM) lipoxin and resolvins E and D respectively, therefore it participates in anti-inflammatory responses (PubMed:17114001, PubMed:21206090, PubMed:31664810, PubMed:32404334, PubMed:8615788). Oxidation of DHA directly inhibits endothelial cell proliferation and sprouting angiogenesis via peroxisome proliferator-activated receptor gamma (PPARgamma) (By similarity). It does not catalyze the oxygenation of linoleic acid and does not convert (5S)-HETE to lipoxin isomers (PubMed:31664810). In addition to inflammatory processes, it participates in dendritic cell migration, wound healing through an antioxidant mechanism based on heme oxygenase-1 (HO-1) regulation expression, monocyte adhesion to the endothelium via ITGAM expression on monocytes (By similarity). Moreover, it helps establish an adaptive humoral immunity by regulating primary resting B cells and follicular helper T cells and participates in the CD40-induced production of reactive oxygen species (ROS) after CD40 ligation in B cells through interaction with PIK3R1 that bridges ALOX5 with CD40 (PubMed:21200133). May also play a role in glucose homeostasis, regulation of insulin secretion and palmitic acid-induced insulin resistance via AMPK (By similarity). Can regulate bone mineralization and fat cell differentiation increases in induced pluripotent stem cells (By similarity).

5-Lipoxygenase also known as 5-LO or 5-LOX is an enzyme that catalyzes the oxidation of arachidonic acid to produce leukotrienes which are signaling molecules in the body. 5-LOX has a molecular weight of approximately 78 kDa. It is mainly expressed in leukocytes like macrophages neutrophils and mast cells. This enzyme plays an important role in the inflammatory response and the regulation of immune functions in these cells.
The activity of 5-Lipoxygenase contributes to the production of leukotrienes which are pivotal in mediating inflammatory and allergic responses. This enzyme operates alone but it often interacts with 5-LOX-activating protein (FLAP) to facilitate the synthesis of leukotrienes efficiently. These interactions suggest that 5-LOX has a significant role in cellular processes related to inflammation and immune reactions.
5-Lipoxygenase is integral to the arachidonic acid metabolic pathway initiating the biosynthesis of leukotrienes from arachidonic acid. This pathway also involves other enzymes like phospholipase A2 which releases arachidonic acid from membrane phospholipids and cyclooxygenase enzymes (COX) which convert arachidonic acid into prostaglandins. The end products of this pathway including leukotrienes manage and resolve inflammation and immune responses illustrating the collaborative effort between these enzymes.
5-Lipoxygenase is significantly linked to inflammatory diseases such as asthma and atherosclerosis. In asthma the overproduction of leukotrienes due to enhanced 5-LOX activity results in bronchoconstriction and inflammation of the airways. In atherosclerosis leukotrienes contribute to the development and progression of plaques driving chronic inflammation in the vascular system. Additionally through its pathway its activity relates closely to cyclooxygenase enzymes showing its importance in disease mechanisms targeted by anti-inflammatory therapies.
