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.
