Bioactivity
20 units/mg protein - One unit is defined as the amount of enzyme that consumes 1.0 nmol of oxygen per min at 25 DEG C in 50 mM Tris-HCl, 100 uM arachidonate, 2 mM CaCl2, 1 mM ATP, 250 uM oxygen. Oxygen consumption can be measured using a oxygraph equipped
Biological Significance
5-lipoxygenase (5-LO) catalyzes the formation of 5(S)-HpETE from arachidonic acid and its subsequent conversion to leukotriene A4. It is localized in the cytosol of resting human and rat peripheral blood neutrophils, whereas it is found in the nucleus in rat basophilic leukemia cells and human alveolar macrophages. Upon stimulation of the cell, 5-LO translocates to the nuclear membrane where it is found in association with 5-LO activating protein (FLAP) and with the 85 kDa cPLA2.
Expression System
Baculovirus

NCBI Description

This gene encodes a member of the lipoxygenase gene family and plays a dual role in the synthesis of leukotrienes from arachidonic acid. The encoded protein, which is expressed specifically in bone marrow-derived cells, catalyzes the conversion of arachidonic acid to 5(S)-hydroperoxy-6-trans-8,11,14-cis-eicosatetraenoic acid, and further to the allylic epoxide 5(S)-trans-7,9-trans-11,14-cis-eicosatetrenoic acid (leukotriene A4). Leukotrienes are important mediators of a number of inflammatory and allergic conditions. Mutations in the promoter region of this gene lead to a diminished response to antileukotriene drugs used in the treatment of asthma and may also be associated with atherosclerosis and several cancers. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

Product Notes

The ALOX5 alox5 (Catalog #AAA537729) is an Active Protein produced from Human and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's 5-Lipoxygenase can be used in a range of immunoassay formats including, but not limited to, User optimized. Researchers should empirically determine the suitability of the ALOX5 alox5 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "5-Lipoxygenase, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
