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). Tg1 does not show bradykinin-potentiating effects. 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. In the N-terminal section; belongs to the bradykinin-potentiating peptide family. In the C-terminal section; belongs to the natriuretic peptide family.
