Abstract:
An enkephalin-containing peptide originating from ovine adrenal proenkephalin has been purified and sequenced. The sequence of the peptide is: GLY-GLY-GLU-VAL-LEU-GLY-LYS-ARG-TYR-GLY-GLY-PHE-MET (preproenkephalin 128-140) which represents a portion of peptide F (preproenkephalin 107-140). This peptide has a sequence identical to that of bovine preproenkephalin 128-140 while it differs from the corresponding human sequence in positions 129, 131 and 133.
