(a) Aminoacylation reaction of LeuRS. (b) Comparison of Leu-AMP and TM84—differences in red. (c) Inhibition of LeuRSAt (4 nM) aminoacylation reaction +/− TM84 (3 nM). Error bars on the initial rate time points represent standard deviation, n=3. (d) The TM84 dose–response curve of LeuRSAt (4 nM) aminoacylation reaction was fit to the Morrison equation for tight-binding inhibitors (equation (1)), indicating a Ki app of 0.3±0.1 nM.
