CC   -!- FUNCTION: Type IV dipeptidyl-peptidase which removes N-terminal
CC       dipeptides sequentially from polypeptides having unsubstituted N-
CC       termini provided that the penultimate residue is proline.
CC       {ECO:0000269|PubMed:15812650}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Release of an N-terminal dipeptide, Xaa-Yaa-|-Zaa-, from a
CC         polypeptide, preferentially when Yaa is Pro, provided Zaa is neither
CC         Pro nor hydroxyproline.; EC=3.4.14.5;
CC   -!- SUBCELLULAR LOCATION: Vacuole membrane {ECO:0000250}; Single-pass type
CC       II membrane protein {ECO:0000250}. Note=Lysosome-like vacuoles.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase S9B family. {ECO:0000305}.
