The effect of tRNA modifications on decoding by M. mycoides tRNAGly UCC. (A) The M. mycoides tRNAGly UCC carrying different sets of modifications were tested for their capability to decode the synonymous glycine codons. [35S]-Met labelled peptides were quantified and normalized to the peptide yields resulting from the GGA containing mRNA. Open circles indicate datapoints shown in the representative gels. (B) Depletion of the three E. coli tRNAGly isoacceptors within E. coli tRNA bulk was rescued with the differently modified M. myocides tRNAGly. The fLuc activities were normalized to the unmodified tRNA sample. (A, B) Mean of individual datapoints with standard deviation is shown. Significance was tested by ANOVA ((A) 0.000424 (left); 0.000782 (right); (B) 0.000722) followed by Dunnett's test (0.001 ‘***’, 0.01 ‘**’, 0.05 ‘*’, >0.05 ‘ns’).
