This peptide evokes slight hypotension (-2 mmHg), when injected alone into rats. It has no bradykinin-potentiating effect, when 60 nmol of BPP-11h are coinjected with 0.5 ug of bradykinin into rats. It inhibits angiotensin converting enzyme (ACE) activity with a K(i)app of 87.07 uM. Expressed by the venom gland. Belongs to the bradykinin-potentiating peptide family.
