Impact of specific nucleotides in the anticodon loop on the initial aminoacylation rates of tRNAGln. The third nucleotide of the tRNAGln anticodon G36, G37 and U38, were individually mutated to the corresponding nucleotides in tRNAGlu2 (G36C, G37A, U38C) and assayed with both GluRS1 (white bars) and GluRS2 (black bars). These mutations did not impact the substrate specificity of tRNAGln. Data to the left of the dashed line are reproduced from Figures 1 and 2 for comparison. Error bars represent standard deviation from triplicate assays.
