THE ORIGINAL MOLECULAR REPLACEMENT WAS CARRIED OUT WITH A LOWER RESOLUTION DATASET. DUE TO LARGE VARIATIONS IN THE CELL PARAMETERS, EACH NEW DATASET WAS RE-SOLVED BY MOLECULAR REPLACEMENT USING A PREVIOUS MODEL. THE SAME R-FREE SET WAS USED IN ALL CASES. STRONG NCS RESTRAINTS WERE USED IN POSITIONAL REFINEMENT. THE COMPLEX WAS DIVIDED INTO 49 TWO-FOLD NCS GROUPS. SPECIFIC RESIDUES NOT OBEYING NCS WERE IDENTIFIED AND RELEASED FROM THE CONSTRAINT. NO NCS RESTRAINT ON B-FACTOR WAS USED. After refinement to convergence against the working set of reflections, the R- and R-Free values of 0.224 and 0.260 were obtained. A final round of positional minimization and restrained B-factor refinement was carried out with identical parameters but against all the data, giving an R-factor of 0.2359. The submitted coordinates are from this final non-cv refinement. Residue (GLU 12 ) and Residue (VAL 17 ) are linked together for chain B and O. Sequence assignment for this fragment is ambiguous. Sequence assignment is also ambiguous for chains I AND V.
