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 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 ...

The metabolism of aged seeds. The free and membrane-bound polyribosomes of germinating rye grains of different ages

open access: yesActa Societatis Botanicorum Poloniae, 2014
Grains of winter rye harvested in 1976, 1978, 1982 and 1984 were studied. Free and membrane-bound polyribosomes were isolated from embryos of imbibing and germinating grains.

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

open access: yes, 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.

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

open access: yes, 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.

Bacterial Longevity Requires Protein Synthesis and a Stringent Response

open access: yesmBio, 2019
Gram-negative bacteria in infections, biofilms, and industrial settings often stop growing due to nutrient depletion, immune responses, or environmental stresses.

An Analysis of the Novel Fluorocycline TP-6076 Bound to Both the Ribosome and Multidrug Efflux Pump AdeJ from Acinetobacter baumannii

open access: yesmBio, 2022
Antibiotic resistance among bacterial pathogens continues to pose a serious global health threat. Multidrug-resistant (MDR) strains of the Gram-negative organism Acinetobacter baumannii utilize a number of resistance determinants to evade current ...

How Cancer Exploits Ribosomal RNA Biogenesis: A Journey beyond the Boundaries of rRNA Transcription

open access: yesCells, 2019
The generation of new ribosomes is a coordinated process essential to sustain cell growth. As such, it is tightly regulated according to cell needs. As cancer cells require intense protein translation to ensure their enhanced growth rate, they exploit ...

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

open access: yes, 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.
