Human leukotriene A4 Hydrolase complex with bestatin, acetate, imidazole, Yb+3 (green) and Zn+2 (grey) ions (PDB entry 1hs6) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Contents 1 Function 2 Relevance 3 Disease 4 Structural highlights Function Leukotriene A4 Hydrolase (LTA4H) is an aminopeptidase which converts leukotriene A4 to leukotriene B4 as part of the arachidonic acid metabolism[1] . LTA4H is a bifunctional Zn+2 enzyme. Relevance LTA4H inhibitors have potential in targeting chronic, autoimmune-driven inflammation[2] . Disease Mutations in LTA4H are linked to susceptibility to asthma and to cardiovascular disease. Structural highlights LTA4H structure shows . The catalytic domain is made of 2 lobes: an α-helical one and an α/β one. The is located between the 2 lobes and [3]. Water molecules shown as red spheres. . .
