We have isolated a neuropeptide, related to the Phe-Met-Arg-Phe-NH2 family, from the thoracic nervous system of the locust, Schistocerca gregaria, using a purification system based on the radioimmunoassay of high pressure liquid chromatography fractions. The primary sequence of this locust peptide is Pro-Asp-Val-Asp-His-Val-Phe-Leu-Arg-Phe-NH2. The bioactivities of the native and synthetic neuropeptide are identical in both the locust heart and hindleg extensor-tibiae muscle bioassays.
我们利用基于高压液相色谱馏分放射免疫分析的纯化系统,从沙漠蝗(Schistocerca gregaria)的胸神经系统中分离出一种与苯丙氨酸 - 蛋氨酸 - 精氨酸 - 苯丙氨酸 - 酰胺(Phe - Met - Arg - Phe - NH2)家族相关的神经肽。这种蝗虫肽的一级序列是脯氨酸 - 天冬氨酸 - 缬氨酸 - 天冬氨酸 - 组氨酸 - 缬氨酸 - 苯丙氨酸 - 亮氨酸 - 精氨酸 - 苯丙氨酸 - 酰胺(Pro - Asp - Val - Asp - His - Val - Phe - Leu - Arg - Phe - NH2)。在蝗虫心脏和后肢伸胫肌生物测定中,天然神经肽和合成神经肽的生物活性相同。
