Abstract
50 S subunits of E. coli ribosomes catalyze the reaction of the 2′(3′)-N-(formyl) methionine ester of adenosine 5′-phosphate and Phe-tRNA resulting in peptide bond synthesis. Cytidine 5′-phosphate stimulates this process on 50 S ribosomal subunits as well as on intact ribosomes. The obtained data show that the areas of the peptidyltransferase donor site which binds the 3′-terminal fragment of peptidyl-tRNA possess completely formed structures on 50 S ribosomal subunits.
