Figure 4.

Investigation of the role of the D-stem and D-loop. Transfer RNAs were constructed to contain only the tRNAGlu2 D-stem (red) or D-Loop (red) in a tRNAGln (black) background. Neither mutant tRNA was a robust substrate for either GluRS1 or GluRS2. Data to the left of the dashed line are reproduced from Figures 1 and 2 for comparison. The white and black bars indicate data obtained from GluRS1 and GluRS2 assays, respectively. Error bars represent standard deviation from triplicate assays.
