Comparison of tRNAGGCAla (wt) to tRNAGGCAla (UA) on the GCC cognate and GCA near-cognate codons. (a) Equilibrium dissociation curves of catalytically inactive ternary complexes binding to the ribosomal entry site. (b) Timecourse of GTP hydrolysis at 1.7 µM ribosomes. (c) Ribosome saturation curve of GTP hydrolysis. (d) Timecourse of dipeptide formation between fMet-tRNAfMet and Ala-tRNAGGCAla. Dipeptide formation for tRNAGGCAla (wt) on the GCA codon could not be fit to a simple exponential, so no line was drawn.
