Figure 1: Three-dimensional reconstruction of the 70S E. coli ribosome in complex with aa-tRNA and EF-Tu. Figure 2: Position of the P-site tRNA. Figure 3: Ternary complex in the A site. Density for ...
In translation, aa-tRNA, EF-Tu and GTP form a ternary complex that binds to the ribosome, allowing codon-anticodon pairing in the 30S ribosomal subunit. Cognate codon recognition triggers fast GTP ...
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 ...
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 ...
Tetrapyrrole biosynthesis in plants, algae, and most bacteria starts from the NADPH-dependent reduction of glutamyl-tRNA by glutamyl-tRNA reductase (GluTR). The GluTR-catalyzed reaction is the ...
Transfer RNAs (tRNAs) are ancient molecules and indispensable components of all living cells. They are found in all three kingdoms of life i.e., in archaea, bacteria and eukaryotes. In a cell, they ...
The tRNA3 Leu gene from yeast contains an intervening sequence of 32 nucleotides not present in mature tRNA. This sequence is transcribed and subsequently removed during the maturation of the RNA. To ...
