THIS CRYSTAL HAS A STACKING FAULT-TYPE DISORDER, WHICH CAN ONLY BE PARTIALLY MODELED. THE OVERLAPPING NCS-RELATED MOLECULES ARE NECESSARY TO MODEL THE DISORDER. Refinement was done with 8 strict NCS matrices as follows: matrix_1 = ( 1.000000 0.000000 0.000000 ) ( 0.000000 1.000000 0.000000 ) ( 0.000000 0.000000 1.000000 ) vector_1 = ( 0.0000 0.0000 0.0000 ) matrix_2 = ( -0.025450 -0.999672 -0.002776 ) ( -0.999629 0.025476 -0.009636 ) ( 0.009703 0.002530 -0.999950 ) vector_2 = ( 95.7336 93.6049 30.5814 ) matrix_3 = ( 0.999874 -0.015577 -0.003041 ) ( -0.015587 -0.999874 -0.003124 ) ( -0.002992 0.003171 -0.999991 ) vector_3 = ( -46.4752 48.4846 0.7945 ) matrix_4 = ( -0.030796 -0.999466 -0.010894 ) ( 0.999470 -0.030907 0.010218 ) ( -0.010550 -0.010574 0.999888 ) vector_4 = ( 48.9629 -45.9887 -29.5468 ) matrix_5 = ( -0.010011 -0.999911 -0.008770 ) ( 0.999838 -0.010141 0.014863 ) ( -0.014951 -0.008620 0.999851 ) vector_5 = ( 48.0912 -47.3711 31.8114 ) matrix_6 = ( 0.999542 -0.030236 -0.001427 ) ( -0.030235 -0.999542 0.001202 ) ( -0.001463 -0.001158 -0.999998 ) vector_6 = ( -45.5886 48.9605 61.9827 ) matrix_7 = ( 1.000000 0.000000 0.000000 ) ( 0.000000 1.000000 0.000000 ) ( 0.000000 0.000000 1.000000 ) vector_7 = ( 0.0000 0.0000 0.0000 ) matrix_8 = ( -0.025450 -0.999672 -0.002776 ) ( -0.999629 0.025476 -0.009636 ) ( 0.009703 0.002530 -0.999950 ) vector_8 = ( 95.7336 93.6049 30.5814 ). Author has stated one complication: Because of the stacking fault-type disorder, the alternate conformers in the current PDB file were assigned different chain IDs during author's refinement. The two alternate conformers of chain C were assigned chain IDs C and F, and the two conformers of chain D were assigned D and E. During the processing of deposition, alternate conformers were used because of the essential PDB format requirement. Therefore, during author's refinement, there were six chains A/B/C/D/E/F. To get the right occupancies during the refinement (1.0 on chains A/B, 0.5 on chains C/D/E/F), author set the occupancies of the starting file at 0.5, and put in two copies of the ncs matrices for the chains A and B with occupancy of 1.0. So there are 8 matrices.
