Abstract

The structure of the hypertrehalosemic neuropeptide of the German cockroach, Blattella germanica, was found to be identical to that of the cockroach species, Blaberus discoidalis and Nauphoeta cinerea (Glp-Val-Asn-Phe-Ser-Pro-Gly-Trp-Gly-Thr-NH2). Since Blattella germanica is not closely related to Blaberus discoidalis and Nauphoeta cinerea, this supports the hypothesis that in this peptide family evolution of peptide structure may be related to evolution of peptide function.
