CC -!- FUNCTION: Exopeptidase which selectively removes arginine and/or lysine
CC residues from the N-terminus of several peptide substrates including
CC Arg(0)-Leu-enkephalin, Arg(0)-Met-enkephalin and Arg(-1)-Lys(0)-
CC somatostatin-14. Can hydrolyze leukotriene A4 (LTA-4) into leukotriene
CC B4 (LTB-4) (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Release of N-terminal Arg and Lys from oligopeptides when P1'
CC is not Pro. Also acts on arylamides of Arg and Lys.; EC=3.4.11.6;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase M1 family. {ECO:0000305}.
