On the Structure of Phenylalanine tRNA from Yeast - FEBS Press In comparison spin label bound to the tRNA molecule is more immobilised and its motion is more isotropic. In addition, the slope of log zC(T) and the nature of the motion changes at a critical temperature T,, which, in the absence of magnesium, varies with ionic strength. In the presence of magnesium T,, is 47.5 "C, whereas the midpoint tem- On the Structure of Phenylalanine tRNA from Yeast - SPRINZL - 1974 ... 2-Thiocytidine incorporated into tRNA Phe from yeast by tRNA nucleotidyl transferase can be alkylated by iodoacetamide and its derivatives. Using this method a spin label was introduced specifically into tRNA Phe and the product, tRNA Phe -C- (s.l.)s 2 C-A, can still be aminoacylated by phenylalanyl-tRNA synthetase.

Transfer RNA (tRNA) - Genome.gov Transfer RNA (abbreviated tRNA) is a small RNA molecule that plays a key role in protein synthesis. Transfer RNA serves as a link (or adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a protein. Each time an amino acid is added to the chain, a specific tRNA pairs with its complementary sequence ...

P Valenzuela, A Venegas, F Weinberg, ... Transfer RNA - Wikipedia Transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes), that serves as the physical link between the mRNA and the amino acid sequence of proteins. Transfer RNA (tRNA) does this by carrying an amino acid to the protein synthesizing machinery of a cell called the ribosome. Structural organization of complexes of transfer RNAs with aminoacyl ... It is proposed that a major part of the binding site for most or all synthetases is along and around the diagonal side of the tRNA structure, which contains the acceptor stem, dihydrouridine stem, and anticodon. This side of the tRNA molecule contains structural features likely to be common for all tRNAs.

Thus a high degree and rate of mischarging of tRNA1^ with phenylalanine would be expected. We found, however, that under standard conditions this misaminoacylation reached only 2 % of homologous charging. Apparently, recognition by phenylalanyl-tRNA synthetase requires additional or alternative structural features in the tRNA. tRNA Structure/tRNA Synthetases - California Lutheran University Structural Features The secondary structure of a typical tRNA, in this case tRNA Ala, is shown in Figure 1, below. The structure consists of hydrogen bonded stems and associated loops, which often contain nucleotides with modified bases (e.g. inosine [I], ribothymidine [T], pseudouridine [Ψ], methylguanosine [D]). Figure 1.

In the latter work, the region studied was limited to 19 nucleotides from G26 to A44 in the anticodon domain of the yeast tRNA Phe molecule. It also established the fact that truncating the molecule at the anticodon stem region does not introduce any serious ... The crystal structure of yeast phenylalanine tRNA at 1.93 A ... The crystal structure of the monoclinic form of yeast phenylalanine tRNA has been redetermined at a resolution of 1.93 A. The structure of yeast tRNAphe described here is more accurate than its predecessors not only because it incorporates higher resolution data, but also because it has been refined using techniques that had not been developed when its predecessors were determined more than 20 years ago.
