空间微重力环境是研究复杂的蛋白质结晶过程和生长高质量蛋白质晶体的理想地方。于1992年8月应用国内研制的装置,在返回式卫星FSW-2上完成了空间蛋白质晶体生长实验。有6种蛋白质在空间长出了晶体,其中蛇毒酸性磷脂酶A_2和鸡蛋清溶菌酶的晶体明显优于地面对照实验长出的晶体,表明空间的微重力利于改进蛋白质晶体的大小、完整性、形态及内部有序性。
Spatial micro-gravity environment is to study the complex protein crystallization process and the ideal place for the growth of high-quality protein crystals. In August 1992, a domestically developed device was used to accomplish the spatial protein crystal growth experiment on the return satellite FSW-2. Six proteins crystallized in space, of which the crystals of snake venom acidic phospholipase A_2 and egg white lysozyme were significantly better than that grown in the ground control experiments, indicating that the microgravity in space is conducive to improving the size, integrity, Form and internal orderliness.
