The elongation and membrane targeting stages of eukaryotic translation. The ribosome is green and yellow, the tRNAs are dark-blue, and the other proteins involved are light-blue. Elongation depends on eukaryotic elongation factors. At the end of the initiation step, the mRNA is positioned so that the next codon can be translated during the ...
In order to maintain a standard for Cell and molecular biology articles a standard color scheme should be used. The accepted colors for cellular locations are described in the table. Colors for other components, such as molecules, can be chosen at the discretion of the designer, however, the following should be considered:
The corresponding mechanisms are primarily targeted on the control of ribosome recruitment on the initiation codon, but can also involve modulation of peptide elongation, termination of protein synthesis, or ribosome biogenesis. While these general concepts are widely conserved, some of the finer details in this sort of regulation have been ...
A musical, Aesop's Fables by British playwright Peter Terson, first produced in 1983, [151] was performed by the Isango Portobello company, directed by Mark Dornford-May at the Fugard Theatre in Cape Town, South Africa, in 2010. [152] The play tells the story of the black slave Aesop, who learns that freedom is earned and kept through being ...
The aa-tRNA, along with particular elongation factors, deliver the amino acid to the ribosome for incorporation into the polypeptide chain that is being produced during translation. Alone, an amino acid is not the substrate necessary to allow for the formation of peptide bonds within a growing polypeptide chain.
EF-Tu (elongation factor thermo unstable) is a prokaryotic elongation factor responsible for catalyzing the binding of an aminoacyl-tRNA (aa-tRNA) to the ribosome. It is a G-protein , and facilitates the selection and binding of an aa-tRNA to the A-site of the ribosome.
Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organization of the protein backbone in 3D and serves as a visual framework for hanging details of the entire atomic structure ...
In addition, repeated AF removal leads to excessive elongation of the fin mesenchyme, potentially because of prolonged exposure of AER signals to the fin mesenchyme. [16] Recently, the AER, which has long been thought to consist of only ectodermal cells, in fact composes of both mesodermal and ectodermal cells in zebrafish.
