Details SEE REMARK 7 THE STRUCTURES WERE CALCULATED USING THE SIMULATED ANNEALING PROTOCOL OF NILGES ET AL. (1988) FEBS LETT. 229, 129 - 136 USING THE PROGRAM (BRUNGER) MODIFIED TO INCORPORATE COUPLING CONSTANT (GARRETT ET AL. (1984) J.MAGN.RESON. SERIES B 104, 99 - 103), CARBON CHEMICAL SHIFT (KUSZEWSKI ET AL. (1995) J.MAGN.RESON. SERIES B 106, 92 - 96) RESTRAINTS, 1H CHEMICAL SHIFT RESTRAINTS (KUSZEWSKI ET AL. (1995) J.MAGN.RESON. SERIES B 107, 293-297; (1996) J.MAGN.RESON. SERIES B 112, 79-81), A CONFORMATIONAL DATABASE POTENTIAL (KUSZWESKI ET AL. (1996) PROTEIN SCI. 5, 1067-108 AND (1997) J.MAGN.RESON. 125, 171-177), AND A TERM FOR THE RADIUS OF GYRATION (KUSZEWSKI ET AL. (1999) J. AM. CHEM. SOC. 121, 2337-2338). THE 3D STRUCTURE OF THE 21 KDA BAF DIMER WAS SOLVED BY MULTI-DIMENSIONAL HETERONUCLEAR-EDITED AND -FILTERED NMR BASED ON 1655 EXPERIMENTAL RESTRAINTS (PER MONOMER): (A) INTRASUBUNIT: 288 SEQUENTIAL (|I-J|=1), 267 MEDIUM RANGE (1 < |I-J| >=5) AND 190 LONG RANGE (|I-J| >5) INTERRESIDUE, AND 7 INTRARESIDUE APPROXIMATE INTERPROTON DISTANCE RESTRAINTS; 64 DISTANCE RESTRAINTS FOR 32 HYDROGEN BONDS; 257 TORSION ANGLE (84 PHI, 78 PSI, 60 CHI1 29 CHI2 AND 6 CHI3) RESTRAINTS; 66 THREE-BOND HN-HA COUPLING CONSTANT RESTRAINTS; 165 (87 CALPHA AND 78 CBETA) 13C SHIFT RESTRAINTS; 44 1H METHYL PROTON CHEMICAL SHIFTS; 259 DIPOLAR COUPLINGS (76 N-H, 76 CALPHA-C', 55 N-C' AND 52 HN-C').
