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.
