Abstract
The ribosomal RNA ("13S" RNA) of the small ribosomal subunit of hamster cell mitochondria has been found to have a distinctive pattern of methylated residues. Each molecule contained, on the average, approximately one residue of m4Cp, m5Cp and m5Up, and two residues of m62Ap. The natural occurrence of m4Cp has not previously been reported; we propose that this nucleotide is homologous to its ribose-methylated congener, m4Cmp, which is characteristic of bacterial 16S ribosomal RNA. We detected neither m4Cp nor m4Cmp in the hamster cell cytoplasmic ribosomal RNA. This is the first documentation of a modified residue present in mitochondrial RNA but absent from the cytoplasmic RNA of the same cells.
