Drug that will inhibit peptidyl transferase
WebThree different types of antibiotics inhibit bacterial protein synthesis by targeting the peptidyl transferase center within the 50S ribosomal subunit. Bacterial expression of a methyltransferase that modifies a specific adenine residue in the 23S rRNA renders all of these drugs ineffective.
