Název v původním jazyce

Water scorpions (Heteroptera, Nepidae) and giant water bugs (Heteroptera, Belostomatidae): Sources of new members of the adipokinetic hormone/red pigment-concentrating hormone family

Popis výsledku v původním jazyce

The giant water bug Lethocerus indicus (family: Belostomatidae) contains a peptide code-named Letin-AKH and the water scorpion Nepa cinerea (family: Nepidae) has the peptide code-named Nepci-AKH. Synthetic peptides were made and co-elution on RP-HPLC with the natural peptide from crude gland extract confirmed the accuracy of the deduced sequence for Letin-AKH and demonstrated that Nepci-AKH contains a Leu residue at position 2 and not an Ile residue. A previously characterized member of the AKH/RPCH family was identified in the stick water scorpion Ranatra linearis: Grybi-AKH has the same mass (919 Da) as Nepci-AKH and differs in two positions from Nepci-AKH (residues 2 and 6). The apparent function of the peptides is to achieve lipid mobilization in the species under investigation; indications for this came from conspecific bioassays using the appropriate synthetic peptides for injecting into the insects. This funct. is very likely linked to dispersal flight metabolism of water bugs.
