Ribosome translocation

WebbThe translocation step of protein elongation entails a large-scale rearrangement of the tRNA-mRNA-ribosome complex. Recent years have seen major advances in unraveling the mechanism of the process on the molecular level. A number of intermediate states have been defined and, in part, characterized structurally. WebbLa translocation, en biologie, décrit deux mécanismes : une étape lors de la synthèse des protéines , lorsque le ribosome se décale de trois nucléotides vers l'extrémité 3' de l'ARN messager....

Webbribosome: The organelle on which mRNA is translated into protein. Consists of a large (60S) and small subunit (40S) which are made up of ribosomal RNA (rRNA) and proteins. The Genetic Code: Translating RNA into Protein How does the nucleotide sequence of RNA specify the specific order of amino acids in a protein? WebbThis implies that translocation is a property inherent to ribosome, and that EF-G may act by lowering a kinetic barrier on binding to the ribosome. Consistent with this, it has been …

WebbOur understanding of protein synthesis has been conceptualised around the structure and function of the bacterial ribosome. This complex macromolecular machine is the target of important antimicrobial drugs, an integral line of defence against infectious diseases. WebbThe tightly coupled assembly, translocation, and disassembly of the ribosome as well as the delivery of tRNA are managed by translation factors and divided into four phases: initiation, elongation, termination, and ribosome recycling ( Hellen, 2024; Shirokikh and Preiss, 2024; Stein and Frydman, 2024 ).
