Comments [?]

Function Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline (By similarity).
Catalytic activity Hydrolyzes Xaa-Pro-|- bonds to release unblocked, N-terminal dipeptides from substrates including Ala-Pro-|-p-nitroanilide and (sequentially) Tyr-Pro-|-Phe-Pro-|-Gly-Pro-|-Ile.
Subunit Homodimer (By similarity).
Subcellular location Cytoplasm (By similarity).
Similarity Belongs to the peptidase S15 family.
