A purified nucleoprotein fragment of the 30 S ribosomal subunit of Escherichia coli.
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.
