酵母tRNAPhe的单斜晶体结构根据2.5埃的一组完整的X射线数据进行改进。分辨率，使用实空间细化以及能量最小化和晶体学最小二乘的组合。这种改进使得残基D16的构象得以确定，并对Y37和A76进行了校正。发现了一个额外的镁结合位点（总共4个），一些水分子和一个可能的精胺分子。
The monoclinic crystal structure of yeast tRNAPhe was refined against a complete set of X-ray data at 2.5 .ANG. resolution, using real-space refinement and a combination of energy minimization and crystallographic least-squares. This refinement has allowed the conformation of residue D16 to be defined and corrections were made to Y37 and A76. An additional magnesium binding site (making a total of 4), a number of water molecules and a possible spermine molecule were found. A revised list of torsion angles is given.
