CC -!- FUNCTION: Probably plays an important role in intracellular peptide
CC degradation. {ECO:0000255|HAMAP-Rule:MF_00504}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Release of an N-terminal amino acid, Xaa, from a peptide or
CC arylamide. Xaa is preferably Glu or Asp but may be other amino acids,
CC including Leu, Met, His, Cys and Gln.; EC=3.4.11.23;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00504};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00504};
CC Note=Binds 2 manganese ions per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00504};
CC -!- SUBUNIT: Homohexamer. {ECO:0000255|HAMAP-Rule:MF_00504}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00504}.
CC -!- SIMILARITY: Belongs to the peptidase M17 family. {ECO:0000255|HAMAP-
CC Rule:MF_00504}.
