(1988) FEBS LETT 229, 317 - 324. MODIFIED TO INCORPORATE COUPLING CONSTANT (GARRETT ET AL. (1994) J. MAGN. RESON SERIES B 104 99 - 103), CARBON CHEMICAL SHIFT (KUSZEWSKI ET AL. (1995) J. MAGN. RESON. SERIES B 106, 92 - 96), AND PROTON CHEMICAL SHIFT (KUSZEWSKI ET AL. (1995) J. MAGN. RESON SERIES B 107, 293 - 297) RESTRAINTS, AND A CONFORMATIONAL DATABASE POTENTIAL TERM (KUSZEWSKI, GRONENBORN & CLORE (1996) PROTEIN SCIENCE IN PRESS). ALL STRUCTURAL STATISTICS ARE GIVEN IN THE REFERENCE. THE 3D STRUCTURE OF THE HUMAN THIOREDOXIN-NFKB PEPTIDE COMPLEX IN SOLUTION BY NMR IS BASED ON 3213 EXPERIMENTAL RESTRAINTS COMPRISING: 2581 STRUCTURE USEFUL INTERPROTON DISTANCE RESTRAINTS 36 RESTRAINTS FOR 18 BACKBONE H-BONDS 321 TORSION ANGLE RESTRAINTS (104 PHI, 76 PSI, 78 CHI1, AND 30 CHI2 FOR HUMAN THIOREDOXIN, AND 11 PHI, 9 PSI, 9 CHI1, AND 4 CHI2 ANGLES FOR THE REF-1 PEPTIDE 86 HN-HALPHA THREE-BOND COUPLING CONSTANTS 100 13CALPHA AND 97 13CB CHEMICAL SHIFT RESTRAINTS. 442 1H CHEMICAL SHIFT RESTRAINTS (MADE UP OF 113 CAH, 67 METHYL GROUPS AND 262 OTHER NON-EXCHANGEABLE PROTONS). THE BREAKDOWN OF THE INTERPROTON DISTANCE RESTRAINTS IS AS FOLLOWS: INTRAMOLECULAR HTRX RESTRAINTS: 534 SEQUENTIAL 539 SHORT RANGE (1 < |I-J|<=5) 688 LONG RANGE (|I-J|>5) 682 INTRARESIDUE INTRAMOLECULAR PEPTIDE RESTRAINTS: 83 INTERMOLECULAR HTRX-NFKB: 55 THE STRUCTURE FOUND IN THIS ENTRY IS THE RESTRAINED MINIMIZED AVERAGE STRUCTURE: (SA)R. THIS IS OBTAINED BY FIRST AVERAGING THE COORDINATES OF THE INDIVIDUAL 35 DYNAMICAL SIMULATED ANNEALING SA STRUCTURES BEST FITTED TO RESIDUES 1 - 105 OF HTRX AND RESIDUES 57 - 67 OF THE PEPTIDE AND SUBJECTING THE RESULTING COORDINATES TO RESTRAINED MINIMIZATION. THE LAST NUMBER COLUMN IN THIS SET OF COORDINATES (THE B-FACTOR COLUMN IN X-RAY STRUCTURES) GIVES THE AVERAGE RMS DIFFERENCE BETWEEN THE INDIVIDUAL SA STRUCTURES AND THE MEAN STRUCTURE. |
