CC   -!- FUNCTION: Removes N-terminal dipeptides sequentially from polypeptides
CC       having unsubstituted N-termini provided that the penultimate residue is
CC       proline. {ECO:0000255|HAMAP-Rule:MF_00698}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolyzes Xaa-Pro-|- bonds to release unblocked, N-terminal
CC         dipeptides from substrates including Ala-Pro-|-p-nitroanilide and
CC         (sequentially) Tyr-Pro-|-Phe-Pro-|-Gly-Pro-|-Ile.; EC=3.4.14.11;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00698};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00698}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00698}.
CC   -!- SIMILARITY: Belongs to the peptidase S15 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00698}.
