Table 3. Refinement of the intermediate structures.
| Refinement data | IS2 | IS3 |
|---|---|---|
| Factor e | 7 | 11 |
| Resolution, Å | 1.9 | 1.9 |
| Rwork,* % | 24.5 | 24.2 |
| Rfree,* % | 28.9 | 25.9 |
| NH2O | 89 | 89 |
Factor e is defined and determined as described in Materials and Methods.
Rwork/free = Σ ∥Fobs| -|Fcalc∥/Σ|Fobs|,|Fobs| are the Laue amplitudes,|Fcalc| are calculated from the atomic structure. Rfree was determined from 5% of the data.
