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. THE STRUCTURE OF THE COMPLEX WAS SOLVED ON THE BASIS OF 70 INTERMOLECULAR RESTRAINTS 1
