摘要：

A novel pheromonotropic neuropeptide has been isolated from a head extract of the armyworm larvae, Pseudaletia separata, by a seven step purification procedure using an in vivo assay with decapitated female moths of Bombyx mori. Amino acid sequence analysis and comparison with synthetic peptides established the primary structure of the peptide, termed Pseudaletia pheromonotropin (Pss PT), as H-Lys-Leu-Ser-Tyr-Asp-Asp-Lys-Val-Phe-Glu-Asn-Val-Glu-Phe-Thr-Pro-Arg-Leu-NH2. Pss PT is structurally related to leucopyrokinin, an insect myotropic neuropeptide, and possesses the C-terminal pentapeptide, Phe-Thr-Pro-Arg-Leu-NH2, responsible for the biological activity. © 1992.
