How is gtp used during elongation

WebSince GTP concentration in the cytoplasm is significantly lower than that of ATP, it is used for specific functions in cell metabolic processes. It's principle use is in protein synthesis when coupled with IF2 during ribosomal initiation, Ef-Tu and Ef-G during elongation and ; RF3 during termination. 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 …

WebGTP is used in protein synthesis. During initiation of translation, the GTP is associated with an initiation factor 2 (IF2) and is hydrolyzed upon the assembly of the initiation ribosomal complex. During elongation, GTP facilitates the binding of a new aminoacyl tRNA to the A site of a ribosome. Web28 jan. 2024 · During 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.
