XRAY DIFFRACTION ANALYSES OF PLANT VIRUSES & HUMAN RIBOSOMAL SUBUNITS

核糖体是蛋白质和rna链的复杂组合。 它们负责蛋白质的合成。低分辨率 结构图，它是通过合并来自 许多单独的结构研究，还不足以 阐明核糖体的许多最重要的结构/功能 关系。只有核糖体的原子分辨率结构才能 回答这些问题。我们计划生长核糖体的晶体 培养的人(HeLa)细胞亚基。亚基已经被 提纯，结晶条件将很快进行测试。

Ribosomes are the complex assemblages of proteins and RNA chains which are responsible for the synthesis of proteins. Low-resolution structural maps, which have been generated by merging the data from many separate structural studies, have not been sufficient to elucidate many of the ribosome's most important structure/function relations. Only atomic-resolution structure of the ribosome can answer these questions. We plan to grow crystals of ribosomal subunits from cultured human (HeLa) cells. Subunits have been purified, and crystallization conditions will soon be tested.
