The atomic coordinates of yeast phenylalanine transfer RNA (tRNA) as well as the torsion angles of the polynucleotide chain are presented as derived from an x-ray diffraction analysis of orthorhombic crystals. A comparison is made between the coordinates obtained from analysis of monoclinic crystals of the same material. It is concluded that the molecule has substantially the same form in the orthorhombic and the monoclinic lattices, except for differences found between residues at the 3' end of the polynucleotides chain. A number of observations are made concerning hydrogen bonding interactions which may account for many of the residues conserved in all tRNA sequences.
本文给出了酵母苯丙氨酸转移核糖核酸（tRNA）的原子坐标以及多核苷酸链的扭转角，这些数据来自于对正交晶体的X射线衍射分析。同时，对由相同材料的单斜晶体分析得到的坐标进行了比较。得出的结论是，除了在多核苷酸链3'端的残基之间存在差异外，该分子在正交晶格和单斜晶格中的基本形态相同。此外，还对氢键相互作用进行了一些观察，这些相互作用可能解释了所有tRNA序列中许多保守的残基。
