WebGuanosine triphosphate (GTP), which is a purine nucleotide triphosphate, acts as an energy source during translation—both at the start of elongation and during the ribosome’s translocation. Binding of the mRNA to the … Web19 jan. 2024 · During elongation, elongation factor Tu (EF-Tu, eEF1A in eukaryotes) is used to deliver aminoacyl-tRNA (aa-tRNA) to the A-site of the ribosome, and elongation …

Why is GTP, rather than ATP, used in nuclear transport?

WebOne GTP is hydrolyzed to GDP as each successive amino acid-tRNA complex attaches to the A site of the ribosome. A second GTP is broken down to GDP as the ribosome moves to each new codon in the mRNA. One ATP is hydrolyzed to AMP during amino acid activation. Thus, the formation of each peptide bond uses 3 high-energy molecules, one ATP and … WebDuring the elongation stage of translation, GTP is used as an energy source for the binding of a new amino-bound tRNA to the A site of the ribosome. GTP is also used as an energy source for the translocation of the ribosome towards the 3' end of the mRNA.

Web12 sep. 2006 · Translocation is promoted by elongation factor G (EF-G), a large, five-domain GTPase that hydrolyzes GTP during the reaction. According to pre-steady-state kinetic analyses, EF-G binds to the pretranslocation ribosome in the GTP-bound form and subsequent rapid GTP hydrolysis precedes translocation (1, 2). WebDuring polypeptide lengthening, elongation factors EF-Tu and EF-G consecutively interact with the bacterial ribosome. EF-Tu binds and delivers an aminoacyl-tRNA to the ribosomal A site and EF-G helps translocate the tRNAs between their binding sites after the peptide bond is formed. These processes occur at the expense of GTP.

Web30 nov. 2024 · Revisions: 40. Translation is the process by which the genetic code contained within a messenger RNA (mRNA) molecule is decoded to produce a specific sequence of amino acids in a polypeptide chain. It occurs in the cytoplasm following DNA transcription and, like transcription, has three stages: initiation, elongation, and termination. WebThe E site is the site from which the ‘uncharged’ tRNAs leave during elongation. Factor IF-1 binds at the A site and prevents tRNA binding at this site during initiation. The IF-2 which has combined with GTP, permits the initiator tRNA (tRNA fMet ) to bind to the 30S ribosomal subunit (Fig. 8.14).
