Protein attributes

Sequence length	617 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Aminopeptidase that preferentially cleaves tripeptides. Also has low epoxide hydrolase activity (in vitro). Can hydrolyze an epoxide moiety of LTA₄ to form LTB₄ (in vitro) By similarity.
Catalytic activity	(7E,9E,11Z,14Z)-(5S,6S)-5,6-epoxyicosa-7,9,11,14-tetraenoate + H₂O = (6Z,8E,10E,14Z)-(5S,12R)-5,12-dihydroxyicosa-6,8,10,14-tetraenoate.
Cofactor	Binds 1 zinc ion per subunit By similarity.
Pathway	Lipid metabolism; leukotriene B4 biosynthesis.
Subcellular location	Cytoplasm By similarity. Nucleus By similarity.
Sequence similarities	Belongs to the peptidase M1 family.
Sequence caution	The sequence EAU32245.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence EAU32245.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
