Bradykinin-potentiating peptide 11a Bradykinin-potentiating peptide 14a Bradykinin-potentiating peptide V-2 BPPEA_BOTJA This peptide both inhibits the activity of the angiotensin-converting enzyme and enhances the action of bradykinin by inhibiting the peptidases that inactivate it. It acts as an indirect hypotensive agent. Bradykinin-potentiating peptide 11a-F has much lower activity than BPP-11a.
