EC 3.4.11.25     
Accepted name: β-peptidyl aminopeptidase
Reaction: Cleaves N-terminal β-homoamino acids from peptides composed of 2 to 6 amino acids
Other name(s): BapA (ambiguous)
Comments: Sphingosinicella xenopeptidilytica strain 3-2W4 is able to utilize the β-peptides β-homoVal-β-homoAla-β-homoLeu and β-homoAla-β-homoLeu as sole carbon and energy sources [2].
