To realize the molecular compositions and bio-spinning mechanisms of spidroin in spider major ampullate, the molecular weight and amino acid compositions of spidrion solution were measured and compared with that of dragline silk. The molecular conformations and morphologies of spidroin and dragline silk in different spinning phases were determined by circular dichroism spectroscopy and laser Raman spectroscopy.

本文以广泛分布于我国各地的大腹园蛛为对象，研究了大腹园蛛主腺体内丝蛋白溶液的分子量和氨基酸组成，并利用圆二色光谱和拉曼光谱分析了蜘蛛在不同成丝阶段丝蛋白的分子构象和聚集态结构的变化，以期了解蜘蛛主腺体内丝蛋白的分子组成及其生物纺丝机制。

In this research, the spider silk from the major ampullate gland of native Nephila pilipes was collected via the forced-silking apparatus at the reeling speed of 3 m/min. The obtained silk was dissolved in hexafluoro-isopropanol. The influence of pH and temperature over the secondary structure of the silk protein in solution state was examined via Circular Dichroism. The effect of silk concentration and electrical field strength on the structure conformation of silk protein during film casting process was investigated via FT-IR. During the drying process, the increase of silk concentration and the presence of electric field tend to form β-sheet and β-turn. Finally, the dried film of silk protein was treated with different temperatures and cation solutions to study the post-treatment effects.

本研究所采用之蜘蛛丝蛋白质系取自本土品种人面蜘蛛之大囊壶腺体，以3 m/min之卷丝速度强迫取丝(forced-silking)收集蜘蛛丝，再将纤维溶於六氟异丙醇溶剂中配制成溶液，以圆二色光谱仪分析在不同 pH 值与温度条件下丝蛋白质在溶液中之二级结构变化，再将蜘蛛丝溶液以不同浓度及电场强度下乾燥成薄膜后，以傅立叶红外线光谱仪检测分析丝蛋白质在固体状态下之二级结构，最后以不同温度加温、离子溶液浸泡等条件对乾燥所得之薄膜进行后处理，并分析其二级结构之变化。

It caused aggregation of purple membrane fragments at very low concentration. This effect might be attributed to its positive charges because cationic surfactant DTAB acted the same. On the other hand, melittin seemed to have behavior similar to CHAPS which has a rigid cholane ring,both had little effect on the conformation of retinal chromporphores.In consideration of the two-dimensional crystalline structure of purple membrane,melittin may form a rigid conformation such as α-helix on the surface of the membrane.

通过与三种在结构和电荷上不同的表面活性剂与紫膜的作用相比较，可以年出蜂毒作为带正电荷的分子与同样带正电的表面活性剂DTAB在引起紫膜凝聚方面表现相同；但在对紫膜可见光区的吸收光谱和圆二色谱的影响上却与具有刚性结构的CHAPS相似，表明蜂毒可在紫膜表面以一种刚性较大的构象存在，不能进入膜蛋白流水区的深层。
