Isolation of less than Glu-Gly-Leu-Arg-Trp-NH2 (Antho-RWamide II), a novel neuropeptide from sea anemones

Research output: Contribution to journalJournal articleResearchpeer-review

Using a radioimmunoassay for the peptide sequence Arg-Phe-NH2 (RFamide), a novel peptide has been purified from acetic acid extracts of the sea anemone Anthopleura elegantissima. This peptide has the structure less than Glu-Gly-Leu-Arg-Trp-NH2, and was named Antho-RWamide II. Antho-RWamide II is a neuropeptide. Its structure is closely related to an earlier characterized neuropeptide from Anthopleura less than Glu-Ser-Leu-Arg-Trp-NH2 (Antho-RWamide I).
