Figure 2.
Direct comparisons of rates of RRF/EF-G-induced PoTC (0.2 μM) breakdown on rapid mixing with 3 μM EF-G·GTP and 2 μM RRF. (A) PoTC-thG, as measured by the decrease in mRNA-thG anisotropy (blue line), tRNAPhe(prf) anisotropy (black line) or light scattering (red line). (B) PoTC-SD-F7, tRNAPhe(prf) anisotropy (black line) or light scattering (red line); PoTC-SD-F7-fl, mRNA-thG anisotropy (blue line). Initial values of mRNA and tRNA anisotropy are offset by +20 and +10%, respectively, for clarity.
