General annotation (Comments)

Function

Extracellular dipeptidyl-peptidase which removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline By similarity.

Catalytic activity

Release of an N-terminal dipeptide, Xaa-Yaa-|-Zaa-, from a polypeptide, preferentially when Yaa is Pro, provided Zaa is neither Pro nor hydroxyproline.

Subcellular location

Secreted By similarity.

Sequence similarities

Belongs to the peptidase S9B family.
