Details THE STRUCTURE WAS CALCULATED BY SIMULATED ANNEALING IN TORSION ANGLE SPACE (C. SCHWIETERS AND G.M. CLORE. J. MAGN. RESON., IN PRESS). THE TARGET FUNCTION COMPRISES TERMS FOR NOE RESTRAINTS, TORSION ANGLE RESTRAINTS, CARBON CHEMICAL SHIFT RESTRAINTS (KUSZWESKI ET AL. J. MAGN. RESON. SERIES B 106, 92-96 (1995), J COUPLING RESTRAINTS (GARRETT ET AL. J. MAGN. RESON. SERIES B 104, 99, 103 (1994); DIPOLAR COUPLING RESTRAINTS (CLORE ET AL. J.MAGN.RESON. 131, 159-162 (1998); J.MAGN.RESON. 133, 216-221(1998)), AND RADIUS OF GYRATION (KUSZEWSKI ET AL. JACS 121, 2337 (1999)). THE NON-BONDED CONTACTS ARE REPRESENTED BY A QUARTIC VAN DER WAALS REPULSION TERM (NILGES ET AL. (1988) FEBS LETT. 229, 129-136); THE DELPHIC TORSION ANGLE DATABASE POTENTIAL (KUSZEWSKI & C J. MAGN. RESON. 146, 249 (2000)); AND THE DELPHIC BASE-BASE POSITIONAL DATABASE POTENTIAL (KUSZEWSKI ET AL. JACS 123, 3903 (2001)). IN THIS ENTRY THE SECOND TO LAST COLUMN REPRESENTS THE AVERAGE RMS DIFFERENCE BETWEEN THE INDIVIDUAL SIMULATED ANNEALING STRUCTURES (400 FOR THE WILD TYPE COMPLEX) AND THE MEAN COORDINATE POSITIONS (OBTAINED BY BEST FITTING TO RESIDUES 4-81 OF THE PROTEIN AND 101-128 OF THE DNA). THE ORIENTATION PROVIDED FOR THE MUTANT (1J47) RELATIVE TO THE WILD TYPE (1J46) WAS OBTAINED BY BEST-FITTING TO RESIDUES 4-81 OF THE PROTEIN.
