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 .

Nuclear 80S Ribosomes Present Across the Stages of Cell Cycle in Drosophila Melanogaster Cells
UMYU Journal of Microbiology Research, 2023 Nuclear translation has been a subject of controversy between scientists for over 5 decades. Despite the existence of evidence to the contrary, most biologists agree that translation exclusively takes place in the cytoplasm of eukaryotes.

Ribosome Biogenesis and Cancer: Overview on Ribosomal Proteins [PDF]
International Journal of Molecular Sciences, 2021 Cytosolic ribosomes (cytoribosomes) are macromolecular ribonucleoprotein complexes that are assembled from ribosomal RNA and ribosomal proteins, which are essential for protein biosynthesis. Mitochondrial ribosomes (mitoribosomes) perform translation of the proteins essential for the oxidative phosphorylation system. The biogenesis of cytoribosomes and

Mass spectrometry of ribosomes and ribosomal subunits [PDF]
Proceedings 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.

Structure and function of yeast Lso2 and human CCDC124 bound to hibernating ribosomes
bioRxiv, 2020 Cells adjust to nutrient deprivation by reversible translational shut down. This is accompanied by maintaining inactive ribosomes in a hibernation state, where they are bound by proteins with inhibitory and protective functions.

The ABCs of the ribosome [PDF]
Nature Structural & Molecular Biology, 2014 An ABC protein that binds the ribosomal exit site suggests a new mechanism for direct regulation of translation in response to changing ATP levels in the cell.

Sequence and expression of a microspore cDNA clone with homology to a ribosomal protein
Acta Societatis Botanicorum Poloniae, 2014 A cDNA library was made to RNA from corn anthers containing developing pollen at the uninucleate microspore stage. A randomly selected clone from this library which contained an insert (531 bp) was isolated and sequenced.

The PDB and the ribosome [PDF]
Journal of Biological Chemistry, 2021 This essay, which was written to commemorate the 50th anniversary of the Protein Data Bank, opens with some comments about the intentions of the scientists who pressed for its establishment and the nature of services it provides. It includes a brief account of the events that resulted in the determination of the crystal structure of the large ribosomal

Basic, simple and extendable kinetic model of protein synthesis
Mathematical Biosciences and Engineering, 2019 Protein synthesis is one of the most fundamental biological processes. Despite existence of multiple mathematical models of translation, surprisingly, there is no basic and simple chemical kinetic model of this process, derived directly from the detailed

mBio, 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.
