Throughout the structure ...詳細: The initial structure of the H189Q mutant of the EI dimer was taken from the calculated structures of the wildtype EI dimer summarized in PDB entry 2KX9. Throughout the structure determination, the backbone atomic coordinates of the c-terminus of each EI subunit (residues 262-573) were held fixed in space, while the two subdomains of each n-terminus (residues 25-142 in the alpha subdomain, and residues 1-21 and 147-254 in the alpha-beta subdomain) were treated as rigid bodies. Coordinates in the linker regions (residues 22-24, 143-146, and 255-261) and interfactial sidechains were allowed varying degrees of freedom during the calculation through the use of the internal variable module (IVM) of Xplor-NIH. Model 1 corresponds to the regularized mean of the 100 structures for which data was reported in the primary publication, with the B-factor column representing the per-atom spread (in B-factor units). Model 2 is the lowest energy structure. The calculated structural statistics for the original 96 structures and for the two reported structures are: MODEL 1: SAXS CHI2 Q->0.44: 0.63 SAXS CHI2 FULL RANGE: 0.80 RDC R-FACTOR: 18.76 RDC DA: 11.16 RDC RH: 0.59 MODEL 2: SAXS CHI2 Q->0.44: 0.50 SAXS CHI2 FULL RANGE: 0.72 RDC R-FACTOR: 19.18 RDC DA: 11.15 RDC RH: 0.60 AVERAGE OVER THE FULL 99-MEMBER ENSEMBLE: SAXS CHI2 Q->0.44: 0.58 +/- 0.10 SAXS CHI2 FULL RANGE: 0.76 +/- 0.16 RDC R-FACTOR: 19.02 +/- 0.37 RDC DA: 11.13+/- 0.19 RDC RH: 0.59 +/- 0.02 Entry fitting list: free wildtype EI structures, PDB ID 2KX9 Num. of conformers calculated: 120 / Num. of conformers submitted: 2 / 代表コンフォーマー: 1 Software author list: C.D.
