CC   -!- FUNCTION: This peptide both inhibits the activity of the angiotensin-
CC       converting enzyme (ACE) and enhances the action of bradykinin by
CC       inhibiting the peptidases that inactivate it. It acts as an indirect
CC       hypotensive agent. {ECO:0000269|PubMed:15245866}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:15245866}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC       {ECO:0000305|PubMed:15245866}.
CC   -!- MASS SPECTROMETRY: Mass=1297.5; Method=Electrospray;
CC       Evidence={ECO:0000269|PubMed:15245866};
CC   -!- MASS SPECTROMETRY: Mass=1296.7; Method=Electrospray;
CC       Evidence={ECO:0000269|PubMed:22869554};
CC   -!- SIMILARITY: Belongs to the bradykinin-potentiating peptide family.
