Leukotriene-A(4) hydrolase.
based on mapping to UniProt P09960
(7E,9E,11Z,14Z)-(5S,6S)-5,6-epoxyicosa-7,9,11,14-tetraenoate + H(2)O = (6Z,8E,10E,14Z)-(5S,12R)-5,12-dihydroxyicosa-6,8,10,14-tetraenoate.
-!- A bifunctional zinc metalloprotease that displays both epoxide hydrolase and aminopeptidase activities. -!- It preferentially cleaves tripeptides at an arginyl bond, with dipeptides and tetrapeptides being poorer substrates. -!- It also converts leukotriene A(4) into leukotriene B(4), unlike EC 3.2.2.10 which converts leukotriene A(4) into 5,6-dihydroxy- 7,9,11,14-eicosatetraenoic acid.
