摘要：Two [Met]enkephalin-containing polypeptides have been purified from extracts of bovine and adrenal chromaffin granules. One is 8000 daltons in size and contains the enkephalin sequence at the carboxy terminus. The other (14,000 daltons) has two internal enkephalin sequences and a third sequence at the carboxy terminus. All of these sequences can be released by trypsin, indicating a possible enkephalin precursor role for the polypeptides.
