Webb15 maj 2000 · The mechanism of translocation is thus dictated by ribosomal structure and motion. EF-G (and EF-G:GDP) itself is remarkably similar in structure to the EF-Tu :GTP:tRNA ternary complex which is responsible for loading tRNA substrates into the A site of the ribosome ( Figure 2) [3]. Domain IV of EF-G is a mimic of the anticodon end of a … Webb11 jan. 2024 · Anaplastic lymphoma kinase is a receptor tyrosine kinase belonging to the insulin receptor (IR) kinase superfamily. It highly expresses in adult brain tissue and exerts an important role in the development of the nervous system. Deregulation of ALK originally presents by the identification of at (2;5) chromosomal translocation in anaplastic large …
Webb22 maj 2015 · The ribosome has three binding sites for transfer RNA (tRNA): the aminoacyl (A) site, peptidyl (P) site, and exit (E) site. In each cycle of the peptide chain elongation, an amino acid is delivered to the ribosome at the A site by a cognate aminoacylated tRNA (aa-tRNA) bound with elongation factor Tu (EF-Tu). WebbThe ribosomal translocation involves both intersubunit rotations between the small 30S and large 50S subunits and the intrasubunit rotations of the 30S head relative to the 30S body. However, the detailed molecular mechanism on how the intersubunit and intrasubunit rotations are related to the translocation remains unclear.
WebbHigh-resolution structures at different stages, as well as biochemical, single molecule and computational approaches have highlighted the elasticity of tRNA molecules when bound to the ribosome. It is well acknowledged that the inherent structural flexibility of the tRNA lies at the heart of the protein synthesis process.
