Comments [?]

Function Probably plays an important role in intracellular peptide degradation.
Catalytic activity Release of an N-terminal amino acid, Xaa, from a peptide or arylamide. Xaa is preferably Glu or Asp but may be other amino acids, including Leu, Met, His, Cys and Gln.
Cofactor Mn(2+)
Note: Binds 2 manganese ions per subunit.
Subunit Homohexamer.
Subcellular location Cytoplasm.
Similarity Belongs to the peptidase M17 family.
