The mitochondrial ribosome and ribosomal RNA of the chick [PDF]
FEBS Letters, 1971 Reports have appeared on large molecular weight RNAs associated with the mitochondria of higher organisms. These include HeLa cells [ 1 ] , BHK-2 1 cells [2] , mouse L-cells [3,4] , rat liver [4, S] and Xenopus ovary [6] . This RNA consists of two predominant species found to be 17 S and 13 S by sedimentation [2, 31 .

Epitranscriptomics of Mammalian Mitochondrial Ribosomal RNA
Cells, 2020 Modified nucleotides are present in all ribosomal RNA molecules. Mitochondrial ribosomes are unique to have a set of methylated residues that includes universally conserved ones, those that could be found either in bacterial or in archaeal/eukaryotic ...

Transcription-translation coupling: direct interactions of RNA polymerase with ribosomes and ribosomal subunits. [PDF]
, 2017 In prokaryotes, RNA polymerase and ribosomes can bind concurrently to the same RNA transcript, leading to the functional coupling of transcription and translation.

The 23S Ribosomal RNA From Pyrococcus furiosus Is Circularly Permuted
Frontiers in Microbiology, 2020 Synthesis and assembly of ribosomal components are fundamental cellular processes and generally well-conserved within the main groups of organisms. Yet, provocative variations to the general schemes exist. We have discovered an unusual processing pathway

Autophagy regulates rRNA synthesis
Nucleus, 2022 Autophagy has emerged as a key regulator of cell metabolism. Recently, we have demonstrated that autophagy is involved in RNA metabolism by regulating ribosomal RNA (rRNA) synthesis.

Recognition of Ribosomal RNA Sites in DNA, I. Analysis of the E. coli System [PDF]
, 1965 The evidence recently presented of specific hybridization between bacterial ribosomal RNA and homologous DNA1-3 has indicated the possibility of a biochemical approach to the problem of the identification of ribosomal RNA sites in DNA.

Homoiterons and expansion in ribosomal RNAs [PDF]
FEBS Open Bio, 2015 Ribosomal RNAs in both prokaryotes and eukaryotes feature numerous repeats of three or more nucleotides with the same nucleobase (homoiterons). In prokaryotes these repeats are much more frequent in thermophile compared to mesophile or psychrophile species, and have similar frequency in both large RNAs.

Yeast Rrp8p, a novel methyltransferase responsible for m1A 645 base modification of 25S rRNA [PDF]
, 2012 Ribosomal RNA undergoes various modifications to optimize ribosomal structure and expand the topological potential of RNA. The most common nucleotide modifications in ribosomal RNA (rRNA) are pseudouridylations and 2'-O methylations (Nm), performed by H ...

RNA‐guided nucleotide modification of ribosomal and non‐ribosomal RNAs in Archaea [PDF]
Molecular Microbiology, 2004 SummaryArchaea use ribonucleoprotein (RNP) machines similar to those found in the eukaryotic nucleolus to methylate ribose residues in nascent ribosomal RNA. The archaeal complex required for this 2′‐O‐ribose‐methylation consists of the C/D box sRNA guide and three proteins, the core RNA‐binding aL7a protein, the aNop56 protein and the ...
