Protein: Leucine aminopeptidase (EC 3.4.11.-) (Epoxide hydrolase) (EC 3.3.2.10) (Leukotriene A-4 hydrolase homolog) (LTA-4 hydrolase) (Q9FY49)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Aminopeptidase that preferentially cleaves di- and tripeptides. Also has low epoxide hydrolase activity (in vitro). Can hydrolyze the epoxide leukotriene LTA(4) but it forms preferentially 5,6-dihydroxy-7,9,11,14-eicosatetraenoic acid rather than the cytokine leukotriene B(4) as the product compared to the homologous mammalian enzyme (in vitro).
Subcellular location: Cytoplasm {ECO:0000250}.
