Presence of pancreatic trypsin inhibitor in adrenal medullary chromaffin cells.
A bovine pancreatic trypsin inhibitor was isolated from bovine adrenal medullary chromaffin granules. Its N-terminal sequence is: arg-pro-asp-phe-cys-leu-glu-pro-pro-tyr-thr-gly-pro-cys-lys-ala-arg-ile- arg-tyr- phe-tyr-asn-ala-lys-ala-gly-leu-cys-gln-thr-phe-val-tyr-gly-gly-cys-arg- ala-lys-arg-asn-asn-phe-lys- which corresponds precisely with the N-terminus of Bovine Pancreatic Trypsin inhibitor. The presence of this inhibitor in these granules suggests another method of regulating the prohormone proteases present there.
