Degradation of adipokinetic hormones

Insect Biochemistry and Molecular Biology, 1992
Abstract Homogenates from various tissues of the desert locust, Schistocerca gregaria , produced identical patterns of breakdown products when incubated with the neuropeptide adipokinetic hormone I (AKH I). Comparison of disappearance of AKH I from the incubation medium of semi-isolated and isolated Malpighian tubules (MTs) and fat body pieces ...

Adipokinetic hormones: cell and molecular biology

Experientia, 1992
Adipokinetic hormones AKH I (pGlu-Leu-Asn-Phe-Thr-Pro-Asn-Trp-Gly-Thr-NH2) and AKH II (pGlu-Leu-Asn-Phe-Ser-Trp-Gly-Thr-NH2) are synthesized by neurosecretory cells (NSC) of the corpora cardiaca (CC) in the locust, Schistocerca gregaria. These NSC constitute a homogeneous 'peptide factory' as each cell synthesizes both AKH I and AKH II.

Locust adipokinetic hormones mobilize diacylglycerols selectively

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2010
The diacylglycerols (DG) molecular species and their fatty acid (FA) composition were investigated by electrospray mass spectrometry (ESI-MS) and by gas chromatography with flame ionisation detection (GC-FID) in haemolymph of Locusta migratoria after application of adipokinetic hormones Locmi-AKH-I, -II and -III. The analyses showed (1) a heterogeneous

Adipokinetic Hormones: Coupling between Biosynthesis and Release

Annals of the New York Academy of Sciences, 1999
Abstract: During long‐distance flight of migratory locusts, the dramatic energy demand of the flight muscles is controlled by three adipokinetic hormones (AKHs). These peptide hormones regulate the mobilization of lipid and carbohydrate stored in the fat body to serve as energy substrates for the flight muscles.

SOLID‐PHASE SYNTHESIS OF LOCUST ADIPOKINETIC HORMONE

International Journal of Peptide and Protein Research, 1981
The synthesis of locust adipokinetic hormone by the solid‐phase method is described. The synthetic product has been shown by bioassay to possess lipid‐mobilizing activity identical to that of the natural hormone.

Adipokinetic Hormones in Locusts

1984
The actions of adipokinetic hormones are more diverse than their utilitarian name suggests. We will review here the known actions of these hormones in adult locusts to emphasise their importance in the integrated utilisation of metabolic fuels during flight.

Primary Structures of Locust Adipokinetic Hormones II

Biological Chemistry Hoppe-Seyler, 1985
Adipokinetic hormones II from corpora cardiaca of the locusts Schistocerca gregaria and Locusta migratoria, respectively, have been isolated and their primary structures elucidated. Both octapeptides are N-terminally blocked by a 5-oxoproline (pyroglutamate) residue and had to be cleaved by 5-oxoprolyl-peptidase to make them available for the Edman ...

Mass spectral signature for insect adipokinetic hormones

Rapid Communications in Mass Spectrometry, 2005
Abstract Insect adipokinetic hormones (AKHs) are structurally similar. They consist of 8 to 10 amino acid residues, and are post‐translationally modified at the N‐terminus (pyroglutamic acid) and at the C‐terminus (carboxyamide).

Relative adipokinetic activities of members of the adipokinetic hormone/red pigment concentrating hormone family

Journal of Insect Physiology, 1986
Naturally occurring peptides from the corpora cardiaca of various insect species are compared on the basis of their ability to cause hyperlipaemia in adult male migratory locusts. The peptides studied are the decapeptide adipokinetic hormone I and the octapeptide adipokinetic hormone II from the migratory locust, hypertrehalosaemic hormones I and II ...
