Sequence analyses of adipokinetic hormones II from corpora cardiaca of Schistocerca nitans, Schistocerca gregaria, and Locusta migratoria by fast atom bombardment mass spectrometry

Structures of the second adipokinetic hormones (AKH II's) from three locust species have been assigned by fast atom bombardment mass spectrometry. The AKH II hormone is identical in two Schistocerca species, S. nitans and S. gregaria, but is different in Locusta migratoria. Both AKH II's a...

Zusammenfassung:	Structures of the second adipokinetic hormones (AKH II's) from three locust species have been assigned by fast atom bombardment mass spectrometry. The AKH II hormone is identical in two Schistocerca species, S. nitans and S. gregaria, but is different in Locusta migratoria. Both AKH II's are related to red pigment-concentrating hormone (RPCH) from prawns, Schistocerca AKH II being [Thr 6]-RPCH and Locusta AKH II being [Ala 6]-RPCH. Schistocerca AKH II is also bioactive in Locusta individuals.
