| Leukotriene A4 Hydrolase from Human, Recombinant | Leukotriene A4 Hydrolase human (LTA4H) is a bifunctional zinc metalloenzyme that converts LTA4 into Leukotriene B4, and also demonstrates aminopeptidase activity. Leukotriene B4 is a lipid chemoattractant that plays critical roles in inflammaton, immune responses, host defenses against infections, and lipid homeostasis. Inhibition of LTA4H in a mouse model decreases LTB4 in the airways and attenuates airway inflammation and airway hyperreactivity through modulation of T cell and dendritic cell function. Contains c-terminal his-tag. Applications: Leukotriene a4 hydrolase human (lta4h) is a drug target for anti-inflammation, and for cancer prevention and therapy. it is also suitable for screening inhibitors of leukotriene b4 synthesis. lta4h is used to study allergic asthma and airway hyperresponsiveness.
