Data Collection and Refinement Statistics for CHAO Holoenzyme and Ternary Complexes.

aNumbers in brackets represent data from the highest resolution shell.b, where represents the intensities of a multiply measured reflection hkl and their average.c dRfree is the R-factor calculated from 10% of the data not included in refinement.eThe number of atoms refined is reduced by a factor of four as strict four-fold non-crystallographic symmetry was employed during refinement.
