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. Ref.1

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 Ref.1.

Sequence similarities

Belongs to the peptidase S9B family.

Biophysicochemical properties

pH dependence:

Optimum pH is 7.0. is active between pH 4.0 and 9.0. Ref.1

Sequence caution

The sequence CAA05343.1 differs from that shown. Reason: Frameshift at positions 63 and 87.
