Fig. 4: Kinetics of 60S subunit joining and the subsequent transition into elongation in experiments performed with mis-acylated tRNAiMet.

The cumulative probability distributions of the dwell times for 60S joining (a) and the transition to elongation (b) from experiments performed at 3 mM free Mg2+ and 20 °C with the model mRNA and unlabeled eIF5B. Data points were fitted to a single-exponential equation with the mean times reported in (c). Errors represent 95% confidence intervals, and the number of molecules analyzed (n) are listed in (c).
