title: Isolation and sequence of a non-opioid peptide derived from proenkephalin.
abstract: A non-opioid peptide derived from adrenal proenkephalin has been isolated and sequenced. The sequence of this peptide is Ser-Pro-His-Leu-Glu-Asp-Glu-Thr-Lys-Glu-Leu-Gln (Proenkephalin 168-180). This sequence represents the portion of Peptide I that is cleaved to yield Peptide E. This peptide is processed in a similar manner to the opioid peptides and is present at approximately the same level as Peptide E.
