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. Bradykinin-potentiating peptide 10b-F has much lower
CC activity than the full-length peptide. {ECO:0000269|PubMed:15245866,
CC ECO:0000269|PubMed:17315274, ECO:0000269|PubMed:4334402}.

CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.

CC ECO:0000269|PubMed:17315274}.
CC -!- DEVELOPMENTAL STAGE: This protein seems to be found in both adult and
CC newborn B.jararaca venoms. {ECO:0000269|PubMed:20146532}.
CC -!- MASS SPECTROMETRY: [Bradykinin-potentiating peptide 10b]: Mass=1215.4;
CC Method=Electrospray; Note=BPP-10b.;

CC Evidence={ECO:0000269|PubMed:17315274};
CC -!- MISCELLANEOUS: Bradykinin-potentiating peptide 10b-F is present only in
CC female snakes. {ECO:0000305|PubMed:17315274}.
CC -!- SIMILARITY: Belongs to the bradykinin-potentiating peptide family.
