Abstract

Large single crystals of formylmethionyl transfer RNA have been prepared. An x-ray diffraction study shows that the material crystallizes in a hexagonal lattice with a equal to 170 angstroms, c equal to 234 angstroms. The diffraction pattern extends to spacings just under 20 angstroms at present. The crystals are heavily hydrated, containing 88 percent water.

摘要

已制备出甲酰甲硫氨酰转移核糖核酸的大单晶。X射线衍射研究表明，该物质结晶为六方晶格，a等于170埃，c等于234埃。目前，衍射图谱延伸至间距略低于20埃处。这些晶体严重水合，含水量为88%。
