This 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. Bradykinin-potentiating peptide 10b-F has much lower activity than the full-length peptide. Expressed by the venom gland. This protein seems to be found in both adult and newborn B.jararaca venoms. BPP-10b. BPP-10b. BPP-10b-F. Bradykinin-potentiating peptide 10b-F is present only in female snakes. Belongs to the bradykinin-potentiating peptide family.
