Beta-peptidyl aminopeptidase
Beta-peptidyl aminopeptidase (EC 3.4.11.25, BapA) is an enzyme.[1][2][3][4] This enzyme catalyses the following chemical reaction
- Cleaves N-terminal beta-homoamino acids from peptides composed of 2 to 6 amino acids
Sphingosinicella xenopeptidilytica strain 3-2W4 could use beta-peptides beta-homoVal-beta-homoAla-beta-homoLeu and beta-homoAla-beta-homoLeu as only source of carbon and energy.
