CC -!- FUNCTION: Aminopeptidase that preferentially cleaves di- and
CC tripeptides. Also has low epoxide hydrolase activity (in vitro). Can
CC hydrolyze the epoxide leukotriene LTA(4) but it forms preferentially
CC 5,6-dihydroxy-7,9,11,14-eicosatetraenoic acid rather than the cytokine
CC leukotriene B(4) as the product compared to the homologous mammalian
CC enzyme (in vitro). {ECO:0000250|UniProtKB:Q10740}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=an epoxide + H2O = an ethanediol; Xref=Rhea:RHEA:19037,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:32955, ChEBI:CHEBI:140594;
CC EC=3.3.2.10; Evidence={ECO:0000250|UniProtKB:Q10740};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:Q10740};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250|UniProtKB:Q10740};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q10740}. Nucleus
CC {ECO:0000250|UniProtKB:Q10740}.
CC -!- SIMILARITY: Belongs to the peptidase M1 family. {ECO:0000305}.
