Statistics of the refinement of the atomic model of d-LDH to x-ray diffraction data

Resolution range	20 − 1.9, Å
Protein atoms	8,533
Solvent atoms	392
Unique reflections	76,528
Rwork*	20.1, %
Rfree†	24.5, %
rms deviation bond lengths	0.024, Å
rms deviation bond angles	2.43°
rms deviation between NCS related molecules	0.32, Å

^*R_work = Σ_(h,k,l) ∥F_o| − |F_c∥/Σ_(h,k,l) |F_o|, where F_o and F_c are the observed and calculated structure factors, respectively. 

^† R_free = Σ_(h,k,l)ɛT ∥F_o| − |F_c∥/Σ_(h,k,l)ɛT |F_c|, where T is the test set containing a randomly selected 10% of the observed reflections omitted from the refinement process.
