【摘要】 原子力显微镜(AFM)这种能进行微尺度测量的精密仪器是目前研究晶体生长机理最为有效的方法之一,在晶体生长机理研究中起到了重要的作用,尤其是对于蛋白质晶体生长的研究显得更为突出。分别简明地阐述了利用AFM进行蛋白质晶体生长研究的工作原理,以及在这方面已经取得的研究成果,包括二维台阶生长、螺旋位错生长、法向生长、三维成核生长、台阶发展的不对称性、及杜仲抗真菌蛋白(EAFP)和天花粉蛋白(TCS)晶体生长的新进展。论述了利用空间微重力环境进行蛋白质晶体生长及空间蛋白质晶体生长的科研和应用,指出今后进行蛋白质晶体生长研究的趋势和前景。更多还原

【Abstract】 Atomic Force Microscopy(AFM) plays a very important role in researching crystal growth mechanism, especially protein crystals. The principle of AFM for protein crystal examination is briefly described as well as the importance of research on protein crystal growth, known growth mechanisms including 2-D steps nucleation, spiral dislocation, normal growth, 3-D nucleation and anisotropic development, and latest progress about eucommia antifungal protein(EAFP) and Trichosanthin(TCS) protein crystal growth mechanism, respectively. Finally, protein growth under microgravity environment is also expounded here and their development tendency and practical prospect.更多还原
