REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : X-PLOR 3.851 REMARK 3 AUTHORS : AXEL BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE STRUCTURE IS BASED ON 276 REMARK 3 DISTANCE RESTRAINTS, 240 DERIVED FROM NOE, 33 METAL CLUSTER REMARK 3 RESTRAINTS FROM 113CD HSQC TOCSY AND 6 RESTRAINTS FROM HN-S REMARK 3 HYDROGEN BONDS. A TOTAL OF 27 DIHEDRAL ANGLE RESTRAINTS WAS REMARK 3 APPLIED, 13 PHI, 10 CHI1 AND 4 CYS-CD CHI2 ANGLES. METHYLENE REMARK 3 PROTONS FOR WHICH NO STEREOSPECIFIC ASSIGNMENT COULD BE REMARK 3 OBTAINED WERE TREATED WITH THE FLOATING CHIRALITY PROCEDURE IN REMARK 3 XPLOR.
