ID 3.3.2.6 DE leukotriene-A4 hydrolase. AN leukotriene A4 hydrolase. AN LTA-4 hydrolase. CA H2O + leukotriene A4 = leukotriene B4. CC -!- A bifunctional zinc metalloprotease that displays both epoxide CC hydrolase and aminopeptidase activities. CC -!- It preferentially cleaves tripeptides at an arginyl bond, with CC dipeptides and tetrapeptides being poorer substrates. CC -!- It also converts leukotriene A4 into leukotriene B4, unlike CC EC 3.2.2.10 which converts leukotriene A4 into 5,6-dihydroxy- CC 7,9,11,14-eicosatetraenoic acid.
