Activity

Function: [Bradykinin-potentiating peptide 5a]: Modestly inhibits ACE (with highest affinity for the N-site) and reveals strong bradykinin-potentiating activity. Induces nitric oxide (NO) production depended on muscarinic acetylcholine receptor M1 subtype (CHRM1) a
Mechanism: Negative results: does not bind to type-1 angiotensin-2 receptor (AGTR1).
