tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...
Proceedings of the National Academy of Sciences of the United States of America, Vol. 105, No. 7 (Feb. 19, 2008), pp. 2331-2336 (6 pages) In mammals, many aminoacyl-tRNA synthetases are bound together ...
In cells transfer RNA (tRNA) translates genetic information from the encoding messenger RNA (mRNA) for protein synthesis. New results from ultrafast spectroscopy and in-depth theoretical calculations ...
New results from ultrafast spectroscopy and in-depth theoretical calculations demonstrate that the complex folded structure of tRNA is stabilized by magnesium ions in direct contact with phosphate ...
The structure of a key enzyme involved in protein production is revealed by cryo-electron microscopy (cryo-EM). Using cryo-EM, researchers at Goethe University (Frankfurt, Germany) shed light on ...
The ribosome selects a correct transfer RNA (tRNA) for each amino acid added to the polypeptide chain, as directed by messenger RNA. Aminoacyl-tRNA is delivered to the ribosome by elongation factor Tu ...
Many viruses have genomes made of RNA. In human cells, messenger RNA (mRNA) molecules act as intermediates; cellular machinery copies a DNA sequence into mRNA so that it can then be translated into a ...
Overview of RNA repair – There is an emerging appreciation of the existence of “RNA repair” pathways that rely on RNA ligases to maintain or manipulate RNA structure in response to purposeful RNA ...
