RT   "Annotation of the Chaetomium globosum CBS 148.51 genome.";
RL   Submitted (MAR-2005) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Aminopeptidase that preferentially cleaves tripeptides.
CC       Also has low epoxide hydrolase activity (in vitro). Can hydrolyze
CC       an epoxide moiety of LTA(4) to form LTB(4) (in vitro) (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY: (7E,9E,11Z,14Z)-(5S,6S)-5,6-epoxyicosa-
CC       7,9,11,14-tetraenoate + H(2)O = (6Z,8E,10E,14Z)-(5S,12R)-5,12-
CC       dihydroxyicosa-6,8,10,14-tetraenoate.
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC   -!- PATHWAY: Lipid metabolism; leukotriene B4 biosynthesis.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase M1 family. {ECO:0000305}.
