Tachykinin peptide isolated and purified from the posteriornsalivary gland Octopus vulgaris which is mollusc. The tachykininnpeptide provides a new approach for developing medicaments andnpesticides through studies on the structural activity correlationnat the molecular level, is characterized by:n (1) number of an amino acid resides is 12; (2) N terminal of the peptide is Lys; (3) an amino acid sequence of 5 amino acids from C terminalnis represented by the following amino acid sequence (I),n n(wherein, Xaa is Val, Ile, Phe or Tyr), especially following aminonacid sequence (1) and (2) are provided: |
