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

Journal 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

Acta 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 ...

Conformational Dynamics of the Plug Domain of the SecYEG Protein-conducting Channel [PDF]

, 2011
The central pore of the SecYEG preprotein-conducting channel is closed at the periplasmic face of the membrane by a plug domain. To study its conformational dynamics, the plug was labeled site-specifically with an environment-sensitive fluorophore.

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

Cells, 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 ...

Stochastic theory of protein synthesis and polysome: ribosome profile on a single mRNA transcript

, 2011
The process of polymerizing a protein by a ribosome, using a messenger RNA (mRNA) as the corresponding template, is called {\it translation}. Ribosome may be regarded as a molecular motor for which the mRNA template serves also as the track.

Quantifying the benefit of a proteome reserve in fluctuating environments. [PDF]

, 2017
The overexpression of proteins is a major burden for fast-growing bacteria. Paradoxically, recent characterization of the proteome of Escherichia coli found many proteins expressed in excess of what appears to be optimal for exponential growth.

Orchestrating ribosomal RNA folding during ribosome assembly

BioEssays, 2022
AbstractConstruction of the eukaryotic ribosome is a complex process in which a nascent ribosomal RNA (rRNA) emerging from RNA Polymerase I hierarchically folds into a native three‐dimensional structure. Modular assembly of individual RNA domains through interactions with ribosomal proteins and a myriad of assembly factors permit efficient ...

How bacteria keep proteins moving

eLife, 2017
Bacteria contain large numbers of negatively-charged proteins to avoid the electrostatic interactions with ribosomes that would dramatically reduce protein diffusion.

Truncation of the Mrp20 Protein Reveals New Ribosome‐assembly Subcomplex in Mitochondria [PDF]

, 2011
Mitochondrial ribosomal protein 20 (Mrp20) is a component of the yeast mitochondrial large (54S) ribosomal subunit and is homologous to the bacterial L23 protein, located at the ribosomal tunnel exit site.
