THE 3D STRUCTURE OF THE MU NER PROTEIN BY MULTI-DIMENSIONAL
HETERONUCLEAR NMR IS BASED ON 1546 EXPERIMENTAL RESTRAINTS
COMPRISING THE FOLLOWING: 944 INTERPROTON DISTANCE
RESTRAINTS [251 SEQUENTIAL; 202 SHORT RANGE (1<|I-J|<=5;
157 LONG RANGE (|I-J|>5); AND 334 INTRARESIDUE]; 40
DISTANCE RESTRAINTS FOR 20 BACKBONE HYDROGEN BONDS; 89
TORSION ANGLE RESTRAINTS 56 PHI, 27 CH1 AND 6 CHI2); 46 3
BOND HN-HA COUPLING CONSTANTS; 140 SECONDARY 13C SHIFTS (72
CA AND 68 CB); 287 1H CHEMICAL SHIFTS (74 HA, 39 METHYL AND
174 OTHER, WITH NO EXCHANGEABLE PROTON SHIFTS).
THE STRUCTURE WAS DETERMINED BY SIMULATED ANNEALING
[NILGES, CLORE AND GRONENBORN (1988) FEBS LETT. 229, 317 -
324] USING THE PROGRAM X-PLOR (BRUNGER) MODIFIED TO
INCORPORATE COUPLING CONSTANT [GARRETT ET AL. AND CLORE
(1994) J. MAGN. RESON. B104, 99 - 103], CARBON CHEMICAL
SHIFT [KUSZEWSKI, QIN, GRONENBORN AND CLORE (1995) J. MAGN.
RESON. B106, 92 - 96] AND PROTON CHEMICAL SHIFT
[KUSZEWSKI, GRONENBORN AND CLORE (1995) J. MAGN. RESON.
B107, 293 - 297] RESTRAINTS.
THIS ENTRY CONTAINS THE RESTRAINED REGULARIZED MEAN
STRUCTURE OBTAINED BY AVERAGING THE COORDINATES OF THE 30
SIMULATED ANNEALING STRUCTURES BEST FITTED TO EACH OTHER
(RESIDUES 8 - 66). THE N- AND C-TERMINI ARE DISORDERED,
AND THE NUMBER IN THE LAST COLUMN (THE B- FACTOR COLUMN)
GIVES THE AVERAGE RMS TO THE MEAN COORDINATE POSITIONS. |
