It was sequenced from the retrocerebral corpora cardiaca glands of Sialis lutaria. The peptide sequence was deduced from the MSN electrospray mass spectra as that of an octapeptide: pGlu-Ile/Leu-Thr-Phe-Thr-Pro-Ser-Trp amide. The amino acid at position 2, Leu or Ile, was solved by comparing retention time on reversed-phase HPLC and establishing co-elution with the synthetic Leu2-peptide. The primary structure is identical to that predicted from genome information for the adipokinetic hormone of the yellow fever mosquito, Aedes aegypti. Since alderflies are not known for their active flight metabolism but produce a rather high number of eggs, it is anticipated that the alderfly is a good study object to establish a possible role of the novel peptide to regulate fat mobilization from the fat body and transport into the egg, thereby playing a role in the control of reproductive processes.
