Novel Tachykinin Peptides, Precursor Peptides Thereof And Genes Encoding The Same

Abstract

Tachykinin peptide isolated and purified from the posterior salivary gland Octopus vulgaris which is mollusc. The tachykinin peptide provides a new approach for developing medicaments and pesticides through studies on the structural activity correlation at the molecular level, is characterized by: (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 terminal is represented by the following amino acid sequence (I), —Phe-Xaa-Gly-Leu-Met-NH2  (I), (wherein, Xaa is Val, Ile, Phe or Tyr), especially following amino acid sequence (1) and (2) are provided: H-Lys-Pro-Pro-Ser-Ser-Ser-Glu-Phe-Val-Gly-Leu-Met-NH2  (1) H-Lys-Pro-Pro-Ser-Ser-Ser-Glu-Phe-Ile-Gly-Leu-Met-NH2  (2)
