Ribosomal Biogenesis and Heterogeneity in Development, Disease, and Aging

open access: yesEpigenomes, 2023
Although reported in the literature, ribosome heterogeneity is a phenomenon whose extent and implications in cell and organismal biology is not fully appreciated.

Transcriptome-wide sites of collided ribosomes reveal principles of translational pausing

open access: yesbioRxiv, 2019
Translation initiation is considered overall rate-limiting for protein biosynthesis, whereas the impact of non-uniform ribosomal elongation rates is largely unknown. Using a modified ribosome profiling protocol based on footprints from two closely packed

Nuclear 80S Ribosomes Present Across the Stages of Cell Cycle in Drosophila Melanogaster Cells

open access: yesUMYU 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.

Preparation of Biologically Active Arabidopsis Ribosomes and Comparison with Yeast Ribosomes for Binding to a tRNA-Mimic that Enhances Translation of Plant Plus-Strand RNA Viruses

open access: yesFrontiers in Plant Science, 2013
Isolation of biologically active cell components from multicellular eukaryotic organisms often poses difficult challenges such as low yields and inability to retain the integrity and functionality of the purified compound. We previously identified a cap-

A limited concentration range of diaphorin, a polyketide produced by a bacterial symbiont of the Asian citrus psyllid, promotes the in vitro gene expression with bacterial ribosomes

open access: yesMicrobiology Spectrum
Diaphorin is a polyketide produced by “Candidatus Profftella armatura” (Gammaproteobacteria: Burkholderiales), an obligate symbiont of a devastating agricultural pest, the Asian citrus psyllid Diaphorina citri (Hemiptera: Psyllidae).

The Impact of Oxidative Stress on Ribosomes: From Injury to Regulation

open access: yesCells, 2019
The ribosome is a complex ribonucleoprotein-based molecular machine that orchestrates protein synthesis in the cell. Both ribosomal RNA and ribosomal proteins can be chemically modified by reactive oxygen species, which may alter the ribosome′s functions

Ribosomes, Ribosomal Subunits and Ribosomal Proteins from Myxococcus xanthus [PDF]

open access: yesJournal of General Microbiology, 1973
SUMMARY: Polyribosomes and ribosomes were isolated from vegetative Myxococcus xanthus FB and myxospores. The sedimentation coefficients of monoribosomes and ribosomal subunits were the same as those for equivalent particles from Escherichia coli. Conditions for the dissociation of the ribosomes and the unfolding of the subunits (in strong salt or very ...

The influence of exogenous spermidine on polysomes and RNase activity in wheat leaves under water stress conditions short communication

open access: yesActa Societatis Botanicorum Poloniae, 2014
It was found that spermidine (5mM) delivered to wheat seedlings through their roots prior to water stress affected the state of polysomes and ribosomes under water stress conditions, which was manifested in stabilization of 80 S ribosomes and in ...

Does functional specialization of ribosomes really exist?

open access: yesRNA: A publication of the RNA Society, 2019
It has recently become clear that ribosomes are much more heterogeneous than previously thought, with diversity arising from rRNA sequence and modifications, ribosomal protein (RP) content and posttranslational modifications (PTMs), as well as bound ...

microRNAs Mediated Regulation of the Ribosomal Proteins and its Consequences on the Global Translation of Proteins

open access: yesCells, 2021
Ribosomal proteins (RPs) are mostly derived from the energy-consuming enzyme families such as ATP-dependent RNA helicases, AAA-ATPases, GTPases and kinases, and are important structural components of the ribosome, which is a supramolecular ...
