== Function ==
[https://www.uniprot.org/uniprot/BAPA_SPHXN BAPA_SPHXN] Beta-aminopeptidase that can cleave synthetic beta-peptides which consist of backbone-elongated beta-amino acid residues that are not processed by common proteolytic enzymes. Can cleave the beta-peptides beta-homoVal-beta-homoAla-beta-homoLeu and beta-homoAla-beta-homoLeu. Requires a beta-amino acid at the N-terminus of peptide substrates and cleaves the peptide bond between the N-terminal beta-amino acid and the amino acid at the second position of tripeptidic substrates of the general structure H-betahXaa-Ile-betahTyr-OH according to the following preferences with regard to the side chain of the N-terminal beta-amino acid: aliphatic and aromatic > OH-containing > hydrogen, basic and polar.<ref>PMID:16109932</ref> <ref>PMID:17064315</ref>
