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 ...

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.

The ribosome returned [PDF]

Journal of Biology, 2009
Since the mid-1990s, insights obtained from electron microscopy and X-ray crystallography have transformed our understanding of how the most important ribozyme in the cell, the ribosome, catalyzes protein synthesis. This review provides a brief account of how this structural revolution came to pass, and the impact it has had on our understanding of how

Bacterial Longevity Requires Protein Synthesis and a Stringent Response

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

SMN-primed ribosomes modulate the translation of transcripts related to Spinal Muscular Atrophy

Nature Cell Biology, 2019
The contribution of ribosome heterogeneity and ribosome-associated proteins to the molecular control of proteomes in health and disease remains unclear.

Role of the particle's stepping cycle in an asymmetric exclusion process: A model of mRNA translation [PDF]

, 2010
Messenger RNA translation is often studied by means of statistical-mechanical models based on the Asymmetric Simple Exclusion Process (ASEP), which considers hopping particles (the ribosomes) on a lattice (the polynucleotide chain).

Emerging Role of Eukaryote Ribosomes in Translational Control

International Journal of Molecular Sciences, 2019
Translation is one of the final steps that regulate gene expression. The ribosome is the effector of translation through to its role in mRNA decoding and protein synthesis.

Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases

FEBS Letters, EarlyView.
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.
