THE STRUCTURES WERE CALCULATED USING THE SIMULATED ANNEALING PROTOCOL OF NILGES ET AL. (1988) FEBS LETT. 229, 129 - 136 USING THE PROGRAM X-PLOR 3.1 (BRUNGER) MODIFIED TO INCORPORATE COUPLING CONSTANT (GARRETT ET AL. (1984) J. MAGN. RESON. SERIES B 104, 99 - 103) AND CARBON CHEMICAL SHIFT (KUSZEWSKI ET AL. (1995) J. MAGN. RESON. SERIES B 106, 92 - 96) RESTRAINTS. THE COORDINATES OF THE 40 FINAL SIMULATED ANNEALING STRUCTURES ARE PRESENTED IN THIS ENTRY. THE B FACTOR FIELD PRESENTS THE AVERAGE RMS OF THE 40 INDIVIDUAL STRUCTURES ABOUT THE MEAN COORDINATE POSITIONS OBTAINED BY BEST FITTING RESIDUES 76 - 94, 97 - 102, 106 -147, 181 - 191, AND 194 -199. THESE RESIDUES CORRESPOND TO THE NON-MOBILE CORE OF THE PROTEIN AS EVIDENCED BY 15N RELAXATION DATA.X-PLOR

DetailsTHE 3D STRUCTURE OF THE HIV-1 NEF (DELTA2 - 39, DELTA 159 - 173) SOLVED BY MULTI-DIMENSIONAL HETERONUCLEAR-EDITED AND -FILTERED NMR IS BASED ON 1250 EXPERIMENTAL RESTRAINTS: 338 SEQUENTIAL (|I-J|=1), 101 MEDIUM RANGE (1 < |I-J| <=5) AND 245 LONG RANGE (|I-J| >5) INTERRESIDUES AND 70 INTRARESIDUE APPROXIMATE INTERPROTON DISTANCE RESTRAINTS; 64 DISTANCE RESTRAINTS FOR 32 HYDROGEN BONDS; 157 TORSION ANGLE (78 PHI, 10 PSI, 55 CHI1 AND 14 CHI2) RESTRAINTS; 91 THREE-BOND HN-HA COUPLING CONSTANT RESTRAINTS; AND 184 (93 CALPHA AND 91 CBETA) 13C SHIFT RESTRAINTS.
