X-RAY DIFFRACTION	MOLECULAR REPLACEMENT	The free R-factor was calculated in early stages of model building and refinement to monitor the progress. Due to the strong interdependency of structure factors in the presence of high NCS, the free R-factor did not provide any useful information. Therefore, in the later stages of structure refinement, all data were included and no free R factor was calculated.
