Mitochondrial peptide chain elongation factors from Neurospora crassa [PDF]
Two complementary peptide chain elongation factors (G and T) have been isolated from a mitochondrial 100,000 g supernatant. Both factors are specific for 70 S ribosomes and can be crossed with T and G factors from E. coli.

Decreased activity of peptide-elongation factors after treatment with cholesterol esterase. [PDF]
1. Peptide-elongation factors were purified from rat liver and treated with cholesterol esterase and phospholipase A2 immobilized on Sepharose 4B. 2. Binding of L-[3H]-phenylalanyl-tRNA to 40S ribosomal subunits was decreased by approx. 70% and to polyribosomes by 30% in the presence of the binding factor incubated with cholesterol esterase.

Cholesteryl esters are bound by a peptide-initiation and a peptide-elongation factor. [PDF]
Significantly higher quantities of cholesteryl 14-methylhexadecanoate than of cholesteryl laurate and cholesteryl palmitate are bound by a homogeneous peptide-initiation factor and purified peptide-elongation factor 1. Cholesteryl 14-methylhexadecanoate may function as a specific allosteric modifier changing the conformation of protein synthesis ...

Origin of the ribosome specific factors responsible for peptide chain elongation in yeast [PDF]
The factors responsible for polypeptide chain elongation are specific for ribosomes of either the 70 S or the 80 S type [l--4]. Two different sets of elongation factors, one specific for 70 S ribosomes and one for 80 S ribosomes, are present in eukaryotic organisms: in Ne ...

Elongating Effect of the Peptide AEDL on the Root of Nicotiana tabacum under Salinity
The overall survival of a plant depends on the development, growth, and functioning of the roots. Root development and growth are not only genetically programmed but are constantly influenced by environmental factors, with the roots adapting to such ...

The role of molecular chaperone CCT/TRiC in translation elongation: A literature review
Protein synthesis from mRNA is an energy-intensive and strictly controlled biological process. Translation elongation is a well-coordinated and multifactorial step in translation that ensures the accurate and efficient addition of amino acids to a ...

Divergent effects of fluoroaluminates on the peptide chain elongation factors EF‐Tu and EF‐G as members of the GTPase superfamily [PDF]
Fluoroaluminates are thought to mimic the γ‐phosphate of GTP and thus, together with GDP, perturb the functioning of heterotrimeric GTP‐binding G‐proteins. Here we show they do inhibit the ribosome‐stimulated GTPase activity of EF‐G from Escherichia coli via the formation of a stable complex with EF‐G·GDP and ribosomes.
