Bradykinin-potentiating peptide both inhibits the activity of the angiotensin-converting enzyme (ACE) and enhances the action of bradykinin by inhibiting the peptidases that inactivate it. It acts as an indirect hypotensive agent (By similarity). Bradykinin inhibitor peptide antagonizes the vasodilatory actions of bradykinin at the B2 bradykinin receptor. Snake venom natriuretic peptide that exhibits hypotensive and vasodepressor activity. Acts by activating natriuretic receptors (NPR1 and/or NPR2 and/or NPR3) (By similarity). Expressed by the venom gland. Bradykinin-potentiating peptide 1. Bradykinin-potentiating peptide 2. Bradykinin-potentiating peptide 3. Bradykinin-potentiating peptide 4. Bradykinin-potentiating peptide 5. Bradykinin inhibitor peptide. In the N-terminal section; belongs to the bradykinin-potentiating peptide family. In the central section; belongs to the bradykinin inhibitor peptide family. In the C-terminal section; belongs to the natriuretic peptide family.
