RA   Guo C.T.;
RT   "Molecular analysis of the bioactive components in snake venoms.";
RL   Submitted (NOV-2006) to UniProtKB.
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|Ref.1}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|Ref.1}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland. {ECO:0000305|Ref.1}.
CC   -!- SIMILARITY: Belongs to the bradykinin-potentiating peptide family.
CC       {ECO:0000305}.
