Abstract in brief

  • Peptidyl transferase, the enzyme responsible for forming peptide bonds in ribosomes, is unusually resistant to common protein removal methods like phenol extraction and EDTA, suggesting it may not be a traditional protein.
  • Experiments show that ribosomal activity persists even after harsh treatments with proteinase K and SDS, especially in Thermus aquaticus, indicating the core catalytic component might be RNA rather than protein.
  • The activity can be specifically inhibited by antibiotics that target peptidyl transferase, and it is destroyed by ribonuclease T1, supporting the idea that 23S ribosomal RNA plays a key role in this catalytic function.]

Unfortunately it was published in Science, so it is still behind a paywall... pubmed.ncbi.nlm.nih.gov/1604315/
