REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : DGII, DISCOVER DISCOVER REMARK 3 AUTHORS : BIOSYM TECHNOLOGIES REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE TOTAL OF 324 NOE-DERIVED REMARK 3 INTERPROTON DISTANCE RESTRAINTS INCLUDING 33 LONG-RANGE NOE REMARK 3 RESTRAINTS AS WELL AS 11 PHI AND 7 CHI1 TORSION ANGLE REMARK 3 RESTRAINTS WERE USED FOR STRUCTURE DETERMINATION. BACK REMARK 3 CALCULATION OF EXPERIMENTAL NOE SPECTRUM YIELDED THE FINAL R- REMARK 3 FACTORS OF RA=0.641 AND RB=0.157. THE FINAL RMSD VALUES ARE REMARK 3 0.90A AND 1.16A FOR THE BACKBONE AND THE HEAVY ATOMS, REMARK 3 RESPECTIVELY. RESIDUES 12 - 24 ARE EXTREMELY WELL-DEFINED WITH REMARK 3 A BACKBONE RMSD OF 0.56 A WHEREAS THE N-TERMINAL 3 - 11 REMARK 3 DISULFIDE LOOP IS FLEXIBLE POSSESSING A BACKBONE RMSD OF 1.09 REMARK 3 A.
