The mitochondrial ribosome and ribosomal RNA of the chick [PDF]

open access: yesFEBS 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 .

The inhibition of ribosomal ribonuclease by bacterial ribosomes [PDF]

open access: yesBiochemical Journal, 1965
1. A comparison has been made between the ribonuclease activities of untreated ribosomes from Escherichia coli B and Pseudomonas fluorescens and the activities of ribosomes on to which ribosomal ribonuclease from E. coli B has been adsorbed. 2. The normal ribosomes from both species were stable in 5-10mm-Mg(2+) (I0.16) at pH6. The RNA in ribosomes from

A Conundrum of r-Protein Stability: Unbalanced Stoichiometry of r-Proteins during Stationary Phase in Escherichia coli

open access: yesmBio, 2022
Bacterial ribosomes are composed of three rRNA and over 50 ribosomal protein (r-protein) molecules. r-proteins are essential for ribosome assembly and structural stability and also participate in almost all ribosome functions.

Ribosomal proteins: functions beyond the ribosome [PDF]

open access: yesJournal of Molecular Cell Biology, 2015
Although ribosomal proteins are known for playing an essential role in ribosome assembly and protein translation, their ribosome-independent functions have also been greatly appreciated. Over the past decade, more than a dozen of ribosomal proteins have been found to activate the tumor suppressor p53 pathway in response to ribosomal stress. In addition,

Microtubule-dependent ribosome localization in C. elegans neurons. [PDF]

open access: yes, 2017
Subcellular localization of ribosomes defines the location and capacity for protein synthesis. Methods for in vivo visualizing ribosomes in multicellular organisms are desirable in mechanistic investigations of the cell biology of ribosome dynamics. Here,

Mass spectrometry of ribosomes and ribosomal subunits [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
Nanoflow electrospray ionization has been used to introduce intact Escherichia coli ribosomes into the ion source of a mass spectrometer. Mass spectra of remarkable quality result from a partial, but selective, dissociation of the particles within the mass spectrometer.

Incorporation in vivo of 14C-Labelled Amino Acids into the Proteins of Mitochondrial Ribosomes from Neurospora crassa Sensitive to Cycloheximide and Insensitive to Chloramphenicol [PDF]

open access: yes, 1969
Radioactive amino acids were incorporated in vivo into Neurospora crassa cells, and the mitochondrial ribosomes were isolated. The incorporation of radioactivity into the proteins of these ribosomes was inhibited by cycloheximide, but not by ...

The Effects of Deregulated Ribosomal Biogenesis in Cancer

open access: yesBiomolecules, 2023
Ribosomes are macromolecular ribonucleoprotein complexes assembled from RNA and proteins. Functional ribosomes arise from the nucleolus, require ribosomal RNA processing and the coordinated assembly of ribosomal proteins (RPs), and are frequently ...

Mitochondrial Translation Products before and after Integration into the Mitochondrial Membrane in Neurospora crassa [PDF]

open access: yes, 1972
# 1. Nascent translation products on mitochondrial ribosomes were selectively labeled in vivo in the presence of cycloheximide with radioactive leucine. They were isolated together with the ribosomes. # 2.

Transcription-translation coupling: direct interactions of RNA polymerase with ribosomes and ribosomal subunits. [PDF]

open access: yes, 2017
In prokaryotes, RNA polymerase and ribosomes can bind concurrently to the same RNA transcript, leading to the functional coupling of transcription and translation.
