THESE REMARK 3 B-VALUES WERE USED FOR THIS STRUCTURE WITHOUT FURTHER REMARK 3 REFINEMENT. REMARK 3 REMARK 3 THE LOW RESOLUTION OF THE IODOINDOMETHACIN COMPLEX REMARK 3 STRUCTURE PRECLUDED REFINEMENT OF ALL ATOMIC POSITIONS. REMARK 3 RATHER, THE TWO HALVES OF THE DIMER WERE SUBJECTED TO REMARK 3 RIGID BODY REFINEMENT, SUBJECT TO NON-CRYSTALLOGRAPHIC REMARK 3 SYMMETRY CONSTRAINTS. THE DRUG WAS THEN PLACED IN THE REMARK 3 ACTIVE SITE, WHERE CLEAR ELECTRON DENSITY WAS SEEN FOR REMARK 3 FOR THE IODINE ATOM ONLY. THE REMAINDER OF THE DRUG WAS REMARK 3 CONSTRUCTED BY MODEL-BUILDING AND ITS POSITION REFINED REMARK 3 BY RIGID BODY METHODS. THE EXPERIMENTAL ELECTRON DENSITY REMARK 3 DOES NOT ALLOW FOR UNAMBIGUOUS POSITIONING OF THE LIGHT REMARK 3 ATOMS OF THE INHIBITOR. AFTER RIGID BODY MINIMIZATION, REMARK 3 THE STRUCTURE WAS FURTHER REFINED BY ALLOWING ONLY THOSE REMARK 3 ATOMS WITHIN AN 8 ANGSTROM SPHERE CENTERED ON ON THE REMARK 3 INHIBITOR TO MOVE. TWO POSSIBLE CONFORMATIONS OF THE REMARK 3 DRUG WERE FOUND, BOTH OF WHICH WERE CONSISTENT WITH THE REMARK 3 OBSERVED HEAVY ATOM DENSITY; THESE CORRESPOND TO THE CIS REMARK 3 AND TRANS ROTATIONAL CONFORMERS OF THE DRUG.
