Abstract
A '13 S' nucleoprotein fragment was isolated from a nuclease digest of Escherichia coli 30-S ribosomal subunits and purified to gel electrophoretic homogeneity. It contained two polynucleotides, of about 1.1 . 10(5) and 2.5 . 10(4) daltons, which separated when the fragment was deproteinized. The major protein components were S4, S7 and S9/11, with S15, S16, S18, S19 and S20 present in reduced amount.
摘要
从大肠杆菌30-S核糖体亚基的核酸酶消化物中分离出一个“13S”核蛋白片段，并将其纯化至凝胶电泳均一性。它包含两个多核苷酸，分子量约为1.1×10⁵和2.5×10⁴道尔顿，当该片段脱蛋白时会分离。主要蛋白质成分是S4、S7和S9/11，S15、S16、S18、S19和S20的含量较少。
