The deletion of [A7-B7] disulfide bond in proinsulin resulted in a significant decrease of α-helix content of the molecule and a great increase in sensitivity to tryptic digestion.

结果表明，A7 B7二硫键缺失可导致胰岛素原α螺旋明显减少以及对胰蛋白酶的酶切敏感性显著增加，其对胰岛素原结构的影响主要导致了受体结合活性的大幅度降低。

The β-CA of B.napus was located in chloroplast stroma and had the conservative motif Cys-X(subscript n-His-X2-Cys peculiar to β type carbonic anhydrases. In the secondary structure,α-helix, random coil,β-sheet, and β-turn were 39.88%, 39.27%, 16.31%, and 4.53%, respectively. The three-dimensional structure was constructed by homology modeling. The 3-D alignment of β-CA from B.napus and a monomer of β-CA octamer from pea showed that the 3-D structure of β-CA from B.napus could match well with the monomer. The alignment results Implied that β-CA from B.napus was a monomer of the β-CA octamer from B.napus.

预测结果显示，甘蓝型油菜β破酸酐酶是定位于叶绿体基质的蛋白质，具有β类碳酸酐酶所特有的保守性基序Cys-χ-His-χ2-Cys；SOPMA预测二级结构显示α螺旋(39.88%)、随机卷曲(39.27%)、β折叠(16.31%)和β转角(4.53%)；用同源建模法构建了三维结构图；通过VAST矢量比对工具将甘蓝型油菜β碳酸酐酶与模板进行三维结构比对，显示甘蓝型油菜β碳酸酐酶与碗豆β碳酸酐酶同型八聚体中的一个单体很好的匹配，推测甘蓝型油菜β碳酸酐酶全酶也是同型八聚体。

In order to improve the inspection technologies of satellite interference, 5 kinds of technologies of satellite interference and integrated judgement-spectrum analysis, helix inspection, PID, S/N and signal vector were put forward. The automatic inspection system of interference of satellite TV has been built according to these inspected technologies and technology of network. The system adopts comparison of spectrum template, calibration of beaconing, mode identification, telemetering pick-up technology and improve the inspection technology of satellite interference. The alarm limits haw been defined through a lot of emulational tests, so that the system become feasible. The system has a good effect and makes up the blank of inspection technologies of interference in our country to some extent.
