Table 3.
Comparison of the change in the rate of subunit joining calculated using ensemble rates of subunit joining reported in the literature with the change in the occupancy of IF2 on the 30S IC estimated from the present work for various pairs of 30S ICs. The two pairs of 30S ICs that exhibit the largest discrepancies in these two parameters are bolded and italicized.
| Complexes | Change in the Rate of Subunit Joininga |
Change in the IF2 Occupancyb |
|---|---|---|
| 30S IC−3 vs. 30S IC−1/3 | 1.2 | 1.1 |
| 30S IC−3 vs. 30S IC−1 | 4.8 | 1.9 |
| 30S ICC vs. 30S IC−3 | 14.5 | 1.1 |
| 30S IC−1/3 vs. 30S IC−1/3,Met | 72 | 68 |
| 30S IC−3 vs. 30S IC−3,Met | 8.1 | 6.7 |
| 30S IC−3 vs. 30S IC−3,Phe | 10.5 | 8.5 |
| 30S ICC vs. 30S ICC,AUU | 90 | 2 |
