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 (By similarity). {ECO:0000250,
CC ECO:0000269|PubMed:22869554}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC -!- MASS SPECTROMETRY: Mass=1278.7; Method=Electrospray;
CC Evidence={ECO:0000269|PubMed:22869554};
CC -!- SIMILARITY: Belongs to the bradykinin-potentiating peptide family.
CC {ECO:0000305}.
