| THE 3D STRUCTURE OF OXIDIZED HUMAN THIOREDOXIN IN SOLUTION
BY NMR IS BASED ON 3018 EXPERIMENTAL RESTRAINTS COMPRISING:
2649 STRUCTURE USEFUL INTERPROTON DISTANCE RESTRAINTS; 34
RESTRAINTS FOR 17 H-BONDS INVOLVING 7 TIGHTLY BOUND WATER
MOLECULES; 42 RESTRAINTS FOR 21 BACKBONE HYDROGEN BONDS
INVOLVING SLOWLY EXCHANGING AMIDE PROTONS; 278 TORSION
ANGLE RESTRAINTS (104 PHI, 76 PSI, 78 CHI1 AND 20 CHI2);
AND 91 HN-HALPHA THREE-BOND COUPLING CONSTANTS. A
COMPLETE LIST OF EXPERIMENTAL RESTRAINTS AND 1H, 13C AND
15N ASSIGNMENTS HAVE BEEN DEPOSITED WITH THE PROTEIN DATA
BANK.
THE STRUCTURES ARE CALCULATED USING THE HYBRID METRIC
MATRIX DISTANCE GEOMETRY-DYNAMICAL SIMULATED ANNEALING
METHOD DESCRIBED BY: NILGES, M., CLORE, G.M. &
GRONENBORN, A.M. (1988) FEBS LETT 229, 317 - 324. ALL
STRUCTURAL STATISTICS ARE GIVEN IN THE REFERENCE.
THE RESTRAINED MINIMIZED AVERAGE STRUCTURE (SA)R IS
PRESENTED IN PROTEIN DATA BANK ENTRY 1TRS. THIS IS
OBTAINED BY FIRST AVERAGING THE COORDINATES OF THE
INDIVIDUAL 40 DYNAMICAL SIMULATED ANNEALING SA STRUCTURES
BEST FITTED TO RESIDUES 1 - 105, AND SUBJECTING THE
RESULTING COORDINATES TO RESTRAINED MINIMIZATION.
COLUMNS 61 - 65 OF THE COORDINATE RECORDS (THE B VALUE
FIELD IN X-RAY STRUCTURES) IN THE MINIMIZED STRUCTURE
(ENTRY 1TRS) GIVE THE AVERAGE RMS DIFFERENCE BETWEEN THE
INDIVIDUAL SA STRUCTURES AND THE MEAN STRUCTURE. THE
NUMBERS IN THIS FIELD OF THE INDIVIDUAL STRUCTURES (ENTRY
1TRU) HAVE NO MEANING. | |
