The L2 mutants affect tRNA binding and peptidyltransferase activity. (A) Dissociation constants generated by analysis of single-site-binding isotherms of eEF-1A stimulated binding of [14C]Phe-tRNA to ribosomal A-sites.(B) Dissociation constants generated by analysis of single-site-binding isotherms of Ac-[14C]Phe-tRNA to ribosomal P-sites. (C) Characterization of peptidyltransferase activities of wild-type and mutant ribosomes generated by analyses of first order time plots of Ac-[14C]Phe-puromycin formation. Error bars denote mean and standard deviation.
