Abstract: | "A pheromonotropic peptide was isolated from brain-suboesophageal ganglion complexes of the adult female gypsy moth, Lymantria dispar, using a 5-step HPLC purification protocol and an in vivo bioassay in Helicoverpa zea. The intact peptide was sequenced by automated Edman degradation. The L. dispar pheromone biosynthesis activating neuropeptide (Lyd-PBAN) is a C-terminally amidated 33-amino acid peptide with a molecular weight of 3881. The peptide was synthesized using Fmoc procedures. Lyd-PBAN has sequence homology with Hez-PBAN (81.8%) and Bom-PBAN-I (66.7%). All three PBANs share the C-terminal hexapeptide sequence, Tyr-Phe-Ser-Pro-Arg-Leu-NH2. In addition, the C-terminal pentapeptide sequences of Pseudaletia pheromonotropin (Pss-PT), Bombyx diapause hormone (Bom-DH), the locustamyotropins (Lom-MT) and leucopyrokinin (Lem-PK) are identical or have a high degree of homology to the C-terminus of PBANs" |
