uL2 B7b bridge mutants alter the binding of translation elongation factors. Dissociation constants (KD) were generated by analysis of single-site binding isotherms of [14C]Phe-tRNAPhe·eEF1A·GTP (ternary complex) (A), or of eEF2 to the ribosomal A-site (B), and Ac-[14C]Phe-tRNAPhe to the P-site (C). Error bars indicate standard error (n = 4, *P < 0.05, **P < 0.01).
