Details 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. ENTRY 1NEQ IS 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.
