CC   -!- FUNCTION: This peptide evokes transient hypotension (-11 mmHg) similar
CC       to that evoked by 0,5 ug of bradykinin, when injected alone into rats.
CC       It has a high bradykinin-potentiating effect (101%), when 60 nmol of
CC       BPP-10f are coinjected with 0.5 ug of bradykinin into rats. It inhibits
CC       angiotensin converting enzyme (ACE) activity with a K(i)app of 2.32 uM.
CC       {ECO:0000269|PubMed:22869554}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- MASS SPECTROMETRY: Mass=1173.6; Method=Electrospray;
CC       Evidence={ECO:0000269|PubMed:22869554};
CC   -!- SIMILARITY: Belongs to the bradykinin-potentiating peptide family.
CC       {ECO:0000305}.
