Abstract

WE have identified two 50S proteins, L2 and L26-L27, in the peptidyl (P) site of the peptidyl transferase centre of E. coli ribosomes¹ BrAc-³H-Phe-tRNA^phe, a peptidyl-tRNA affinity analogue, was shown to bind specifically to the P site and covalently react with only L2 and L26-L27. The ability of the same molecules of ribosome-bound BrAcPhe-tRNA^phe to participate in dipeptide formation and covalent attachment to ribosomal proteins was the most compelling evidence for functional P site binding.
