CC -!- FUNCTION: Probably plays an important role in intracellular CC peptide degradation (By similarity). CC -!- CATALYTIC ACTIVITY: Release of an N-terminal amino acid, Xaa, from CC a peptide or arylamide. Xaa is preferably Glu or Asp but may be CC other amino acids, including Leu, Met, His, Cys and Gln. CC -!- COFACTOR: Binds 2 manganese ions per subunit (By similarity). CC -!- SUBUNIT: Homohexamer (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the peptidase M17 family.
