متن کاملAllatostatic neuropeptides from the cockroach Blattella germanica (L.) (Dictyoptera, Blattellidae). Identification, immunolocalization and activity.
Four allatostatic neuropeptides were isolated from extracts of the brain of the cockroach Blattella germanica. The primary structures of these peptides were assigned as Leu-Tyr-Asp-Phe-Gly-Leu-NH2 (BLAST-1), Asp-Arg-Leu-Tyr-Ser-Phe-Gly-Leu-NH2 (BLAST-2), Ala-Gly-Ser-Asp-Gly-Arg-Leu-Tyr-Ser-Phe-Gly-Leu-NH2 (BLAST-3) and Ala-Pro-Ser-Ser-Ala-Gln-Arg-Leu-Tyr-Gly-Phe-Gly-Leu-NH2 (BLAST-4). Each of t...
