Method THE STRUCTURE OF THE COMPLEX WAS CALCULATED AS FOLLOWS. FIRST THE STRUCTURE OF THE DIMERIC LACHP62-V52C WAS CALCULATED USING ONLY PROTEIN NMR RESTRAINTS. THE 100 BEST STRUCTURES WERE SELECTED AND DOCKED ONTO THE NONSPECIFIC LAC OPERATOR B-DNA USING SIMULATED ANNEALING. DISTANCE AND PLANARITY RESTRAINTS FOR THE DNA WERE INCORPORATED IN ORDER TO KEEP DNA CLOSE TO B-DNA CONFORMATION.
Details THE STRUCTURE OF THE COMPLEX WAS SOLVED ON THE BASIS OF 70 INTERMOLECULAR RESTRAINTS

Additional NMR Experimental Information
1 THIS STRUCTURE WAS DETERMINED USING STANDARD 2D AND 3D HOMO- AND HETERONUCLEAR TECHNIQUES. 13C-15N LABELED PROTEIN AND UNLABELED NUCLEOTIDE WERE USED. IN ADDITION ISOTOPE FILTER EXPERIMENTS WERE APPLIED TO OBTAIN ADDITIONAL ASSIGNMENTS AND TO ASSIGN INTER-MOLECULAR NOES. FOR FURTHER DETAILS SEE THE REFERENCE DESCRIBING THE STRUCTURES.
