Modelling the effect of ribosome mobility on the rate of protein synthesis [PDF]
Eur. Phys. J. E 44, 19 (2021), 2020 Translation is one of the main steps in the synthesis of proteins. It consists of ribosomes that translate sequences of nucleotides encoded on mRNA into polypeptide sequences of amino acids. Ribosomes bound to mRNA move unidirectionally, while unbound ribosomes diffuse in the cytoplasm.

Frontiers in Cell and Developmental Biology, 2019 Mitochondria exert their many functions through a repertoire of hundreds of proteins. The vast majority of these proteins are encoded in the nuclear genome, translated in the cytosol and imported into the mitochondria. Current models, derived mainly from

mBio, 2021 During nutrient limitation, bacteria produce the alarmones (p)ppGpp as effectors of a stress signaling network termed the stringent response. RsgA, RbgA, Era, and HflX are four ribosome-associated GTPases (RA-GTPases) that bind to (p)ppGpp in ...

Traffic of interacting ribosomes: effects of single-machine mechano-chemistry on protein synthesis [PDF]
Physical Review E 75, 021902 (2007), 2006 Many ribosomes simultaneously move on the same messenger RNA (mRNA), each separately synthesizing the protein coded by the mRNA. Earlier models of ribosome traffic represent each ribosome by a ``self-propelled particle'' and capture the dynamics by an extension of the totally asymmetric simple exclusion process (TASEP).

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 ...

Cell, 2001 The conversion of a ribosomal RNA transcript to a cytoplasmic ribosome requires hundreds of accessory RNA and protein factors. Two papers published recently in Molecular Cell provide first looks at the association of these processing factors with the intermediates in ribosome synthesis (Harnpicharnchai et al., 2001; Bassler et al., 2001).

Acta 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.

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.
