Bradykinin-potentiating peptides 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). Expressed by the venom gland. This protein seems to be found in adult B.jararaca venom but not in newborn snake venom. Belongs to the bradykinin-potentiating peptide family.
