| torsion angle dynamics | THE STRUCTURES ARE BASED ON A TOTAL 729 CONFORMATIONALLY-RESTRICTING NOE-DERIVED DISTANCE CONSTRAINTS, 260 DIHEDRAL ANGLE CONSTRAINTS, AND 50 HYDROGEN BOND CONSTRAINTS (9.3 CONSTRAINTS PER RESIDUE; 1.2 LONG-RANGE CONSTRAINTS PER RESIDUE). STRUCTURE DETERMINATION WAS PERFORMED ITERATIVELY USING AUTOSTRUCTURE (DYANA). THE 10 STRUCTURES WITH THE LOWEST TARGET FUNCTION WERE FURTHER REFINED BY RESTRAINED MOLECULAR DYNAMICS/ENERGY MINIMIZATION IN EXPLICIT WATER (CNS). THE UNSTRUCTURED N- (1 to 17) AND C- (121 to 125) TERMINAL REGIONS OF THE MOLECULE ARE OMITTED FROM THIS DEPOSITION. | VNMR |

| Details | THE STRUCTURE WAS DETERMINED USING TRIPLE-RESONANCE NMR SPECTROSCOPY. AUTOMATIC BACKBONE ASSIGNMENTS WERE MADE USING AUTOASSIGN. MANUAL SIDE CHAIN ASSIGNMENTS. AUTOMATIC NOESY ASSIGNMENTS AS WELL AS DISTANCE AND HYDROGEN BOND CONSTRAINTS WERE DETERMINED USING AUTOSTRUCTURE. DIHEDRAL ANGLE CONSTRAINTS WERE DETERMINED USING HYPER AND TALOS. FINAL STRUCTURE QUALITY FACTORS FOR THE ENSEMBLE (RESIDUES 18 to 120), WHERE ORDERED RESIDUES [S(PHI) + S(PSI) > 1.8] COMPRISE 19-33,42-56,61-62,64-74,77-79,83-119: (A) RMSD FOR ORDERED RESIDUES: BB, 1.2; HEAVY ATOM, 1.7 (B) RAMACHANDRAN STATISTICS FOR ORDERED RESIDUES: MOST FAVORED: 93.0%; ADDITIONALLY ALLOWED: 5.7%; GENEROUSLY ALLOWED, 0.8%; DISALLOWED, 0.5% (C) PROCHECK SCORES FOR ORDERED RESIDUES (RAW/Z-): BB, 0.20/1.10; ALL, -0.02/-0.12. (D) MAGE MOLPROBITY CLASH SCORE (RAW/Z-): 33.54/-4.23. (E) RPF SCORES FOR GOODNESS OF FIT TO NOESY DATA: F-MEASURE, 0.834; RECALL, 0.900; PRECISION, 0.776; DP-SCORE, 0.606. |
