Details THE TARGET FUNCTION COMPRISES TERMS FOR THE NOE-DERIVED INTERPROTON DISTANCE RESTRAINTS, TORSION ANGLE RESTRAINTS, 3JHN-HALPHA COUPLING CONSTANT RESTRAINTS, 13CALPHA/BETA CHEMICAL SHIFT RESTRAINTS, AND RESIDUAL DIPOLAR COUPLING RESTRAINTS (N-H); THE NON-BONDED INTERACTIONS ARE REPRESENTED BY A QUARTIC VAN DER WAALS REPULSION TERM, TORSION ANGLE AND HYDROGEN BONDING DATABASE POTENTIALS OF MEAN FORCE, AND A RADIUS OF GYRATION RESTRAINT. IN THIS ENTRY THE LAST COLUMN REPRESENTS THE AVERAGE RMS DIFFERENCE BETWEEN THE INDIVIDUAL SIMULATED ANNEALING STRUCTURES BEST-FITTED TO RESIDUES 8-65. ONLY RESIDUES 8-68 ARE SHOWN SINCE RESIDUES 1-7 AT THE C-TERMINUS ARE DISORDERED IN SOLUTION EXPERIMENTAL RESTRAINTS: 562 INTERPROTON DISTANCE RESTRAINTS: (173 INTRARESIDUE; 174 SEQUENTIAL, 94 MEDIUM-RANGE, AND 121 LONG-RANGE INTERRESIDUE; 58 DISTANCE RESTRAINTS FOR 29 BACKBONE H-BONDS 202 TORSION ANGLE RESTRAINTS (69 PHI, 55 PSI, 78 CHI) 189 CALPHA/CBETA CHEMICAL SHIFT RESTRAINTS 37 3JHN-HA COUPLING CONSTANT RESTRAINTS 35 RESIDUAL NH DIPOLAR COUPLING RESTRAINTS 135 CA/CB 13C SHIFTS DIPOLAR COUPLING R-FACTOR: 5.5% (DA = -9.7Hz, RHOMBICITY = 0.46)
