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.

Separation and Paired Proteome Profiling of Plant Chloroplast and Cytoplasmic Ribosomes
Plants, 2020 Conventional preparation methods of plant ribosomes fail to resolve non-translating chloroplast or cytoplasmic ribosome subunits from translating fractions.

Mediating Ribosomal Competition by Splitting Pools [PDF]
LCSS Vol 5 Issue 5 (Nov 2020), 2020 Synthetic biology constructs often rely upon the introduction of "circuit" genes into host cells, in order to express novel proteins and thus endow the host with a desired behavior. The expression of these new genes "consumes" existing resources in the cell, such as ATP, RNA polymerase, amino acids, and ribosomes. Ribosomal competition among strands of

Frontiers in Microbiology, 2021 Translation is an important step in gene expression. Initiation of translation is rate-limiting, and it is phylogenetically more diverse than elongation or termination. Bacteria contain only three initiation factors. In stark contrast, eukaryotes contain

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.

Characterization of HicAB toxin-antitoxin module of Sinorhizobium meliloti
BMC Microbiology, 2019 Background Toxin-antitoxin (TA) systems are little genetic units generally composed of two genes encoding antitoxin and toxin. These systems are known to be involved in many functions that can lead to growth arrest and cell death.

Ribosomal proteins: functions beyond the ribosome [PDF]
Journal 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,

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

The kinetic mechanism of bacterial ribosome recycling. [PDF]
, 2017 Bacterial ribosome recycling requires breakdown of the post-termination complex (PoTC), comprising a messenger RNA (mRNA) and an uncharged transfer RNA (tRNA) cognate to the terminal mRNA codon bound to the 70S ribosome.
