PHYSICAL CHEMISTRY OF VIRUSES AND THEIR COMPONENTS

我们建议对大多数可用的丝状细菌进行结构研究， 病毒，其细胞内前体复合物之间的DNA结合 蛋白质和后代DNA，以及一些人的基因组。 所有的病毒 以革兰氏阴性菌为宿主，其中几种是致病性的 无论是植物还是动物。 所有的病毒都有相同的基本 全部都含有一个单链DNA基因组， 由数千个相同的亚基组成的鞘。 技术如 超离心，电子显微镜，光散射，CD和 荧光光谱，X射线衍射和其他技术将被 用于确定基本结构参数。 研究 各种病毒体组分之间的完整病毒体之间的相互作用，以及 DNA结合蛋白和核酸之间的关系也被提出。 的 主要结构蛋白的氨基酸序列有待确定 通过DNA测序和蛋白质测序技术。 理论工作 将针对这些结构的统一理论， 相似的，但在细节上不同的，具有相同功能的核蛋白， 以及对它们进化关系的理解。

We propose structural studies on most available filamentous bacterial viruses, on their intracellular precursor complexes between DNA binding proteins and progeny DNAs, and on the genomes of some. All of the viruses have Gram-negative bacteria as hosts, several of which are pathogenic either in plants or animals. All of the viruses have the same basic overall morphology and all contain a single-stranded DNA genome packed in a sheath of thousands of identical subunits. Techniques such as ultracentrifugation, electron microscopy, light scattering, CD and fluorescence spectroscopy, X-ray diffraction, and other techniques will be applied to determine fundamental structure parameters. Studies on interactions, between intact virions between various virion components, and between the DNA binding proteins and nucleic acids are also proposed. The amino acid sequences of the major structural proteins are to be established through DNA sequencing and protein sequencing techniques. Theoretical work will be directed toward unified theories of the structures of these similar, but in detail diverse, nucleoproteins having the same function, and toward understanding of their evolutionary relationships.
