Biological and Biochemical Foundations
Formation of peptide bonds during translation is catalyzed by:
- Aaminoacyl-tRNA synthetases bound at the ribosomal A site.
- Belongation factor EF-Tu, using energy from GTP hydrolysis.
- CrRNA of the large ribosomal subunit.
- Dproteins of the small ribosomal subunit that bind mRNA.
Show the answer and explanation
Answer: C. The peptidyl transferase center lies in the large subunit and is made of rRNA (23S rRNA in bacteria, 28S in eukaryotes); no protein side chain is close enough to catalyze the reaction, so the ribosome is a ribozyme. The energy for the bond comes from the high-energy ester linking the amino acid to its tRNA, created by the aminoacyl-tRNA synthetase.
