simulated annealing	THE STRUCTURES WERE CALCULATED USING THE SIMULATED ANNEALING PROTOCOL OF NILGES ET AL. (1988) FEBS LETT. 229, 129 - 136 AND PROTEIN ENGINEERING 2, 27 - 38 USING THE PROGRAM X-PLOR MODIFIED TO INCORPORATE COUPLING CONSTANT RESTRAINTS (GARRETT ET AL. (1994) J. MAGN RESON. SERIES B 104, 99 - 103), CARBON CHEMICAL SHIFT RESTRAINTS (KUSZEWSKI ET AL. (1995) J. MAGN. RESON. SERIES B 106, 92 - 96) RESTRAINTS, DIPOLAR COUPLING RESTRAINTS (TJANDRA ET AL. (1997) NATURE STRUCT BIOL 4, 732-738) AND A CONFORMATIONAL DATABASE POTENTIAL FOR PROTEINS AND NUCLEIC ACIDS (KUSZEWSKI ET AL. (1996) PROTEIN SCI 5, 1067 - 1080 AND (1997) J. MAGN. RESON. 125, 171-177) THE 3D STRUCTURE OF THE COMPLEX OF THE LEU22VAL AREA DBD-DNA COMPLEX WAS SOLVED BY MULTI-DIMENSIONAL HETERONUCLEAR-EDITED AND -FILTERED NMR IS BASED ON THE FOLLOWING 1128 EXPERIMENTAL RESTRAINTS (A) PROTEIN: 131 SEQUENTIAL (\|I-J\|=1), 63 SHORT RANGE (1 < \|I-J\| >=5), 67 LONG RANGE (\|I-J\|>5), AND 38 INTRARESIDUE APPROXIMATE INTERPROTON DISTANCE RESTRAINTS; NULL 120 TORSION ANGLE RESTRAINTS (53 PHI, 13 PSI, 39 CHI1, 14 CHI2, AND 1 CHI3), 39 THREE-BOND HN-HA COUPLING CONSTANT RESTRAINTS; NULL 75 (41 CALPHA AND 34 CBETA) 13C CHEMICAL SHIFT RESTRAINTS; NULL 49 RESIDUAL N-H DIPOLAR COUPLING RESTRAINTS; 20 DISTANCE RESTRAINTS FOR 10 BACKBONE HYDROGEN BONDS. (B) DNA: 75 INTRARESIDUE, 124 SEQUENTIAL INTRASTRAND AND 22 INTERSTRAND INTERPROTON DISTANCE RESTRAINTS; 63 DISTANCES FOR WATSON-CRICK BASE PAIR HYDROGEN BONDS; 170 TORSION ANGLE RESTRAINTS FOR THE DNA BACKBONE COVERING VALUES CHARACTERISTIC OF BOTH A AND B DNA. (C) 58 INTERMOLECULAR INTERPROTON DISTANCE RESTRAINTS (D) 2 INTERMOLECULAR DISTANCE RESTRAINTS TO PHOSPHATES (E) 8 'REPULSIVE' RESTRAINTS (F) 4 DISTANCE RESTRAINTS FOR 2 INTERMOLECULAR H-BONDS BETWEEN ARG 24 AND BASE OF GUA5.
