Question

18. Why is the proximity between ribosomes and amino acids important for the protein formation? What is the enzyme that catalyzes that reaction?

Answer 1

The proximity between ribosomes and amino acids is important because the enzyme that catalyzes the peptide bond resides in ribosomes. As substrates of these enzymes, amino acids need to bind to the enzyme activation centers.

The enzyme that catalyzes the peptide bond is the peptidyl transferase.
