摘要：

Two peptide inhibitors of juvenile hormone biosynthesis, designated G. bimaculatus allatostatins A1 and A2, have been purified from extracts of the brain of the field cricket Glyllus bimaculatus. The primary structures of these peptides were assigned as Ala-Gln-His-Gln-Tyr-Ser-Phe-Gly-Leu-NH2 (Grb-AST Al) and Ala-Gly- Gly-Arg-Gln-Tyr-Gly-Phe-Gly-Leu-NH2 (Grb-AST A2). Each of the peptides shows C-terminal amino acid sequence similarity to cockroach allatostatins and blowfly callatostatins. The two peptides are potent inhibitors of in vitro juvenile hormone production by corpora allata from virgin females of G. bimaculatus.
