Purity ~90% (SDS-PAGE). LTA4H also known as Leukotriene A-4 hydrolase is a bifunctional enzyme which converts leukotriene A4 to leukotriene B4 and acts as an aminopeptidase. This enzyme belongs to the family of hydrolases, specifically those acting on ether bonds (ether hydrolases). It participates in arachidonic acid metabolism. Source: Recombinant protein corresponding to aa1-611 of human LTA4H, fused to His-tag at N-terminal expressed in E. coli. Molecular Weight: ~71.7kD AA
