REMARK 210 SOFTWARE USED : XWINNMR 3.0, NMRPIPE 2.1, REMARK 210 NMRVIEW 5.0.3, CNS 1.1 REMARK 210 METHOD USED : THE STRUCTURE OF THE COMPLEX REMARK 210 WAS CALCULATED AS FOLLOWS. REMARK 210 FIRST THE STRUCTURE OF THE REMARK 210 DIMERIC LACHP62-V52C WAS REMARK 210 CALCULATED USING ONLY PROTEIN REMARK 210 NMR RESTRAINTS. THE 100 BEST REMARK 210 STRUCTURES WERE SELECTED AND REMARK 210 DOCKED ONTO THE NONSPECIFIC REMARK 210 LAC OPERATOR B-DNA USING REMARK 210 SIMULATED ANNEALING. DISTANCE REMARK 210 AND PLANARITY RESTRAINTS FOR REMARK 210 THE DNA WERE INCORPORATED IN REMARK 210 ORDER TO KEEP DNA CLOSE TO B- REMARK 210 DNA CONFORMATION. REMARK 210 REMARK 210 CONFORMERS, NUMBER CALCULATED : 400 REMARK 210 CONFORMERS, NUMBER SUBMITTED : 20 REMARK 210 CONFORMERS, SELECTION CRITERIA : STRUCTURES WITH THE LOWEST REMARK 210 ENERGY REMARK 210 REMARK 210 BEST REPRESENTATIVE CONFORMER IN THIS ENSEMBLE : 1 REMARK 210 REMARK 210 REMARK: THIS STRUCTURE WAS DETERMINED USING STANDARD 2D AND 3D REMARK 210 HOMO- AND HETERONUCLEAR TECHNIQUES. 13C-15N LABELED PROTEIN REMARK 210 AND UNLABELED NUCLEOTIDE WERE USED. IN ADDITION ISOTOPE FILTER REMARK 210 EXPERIMENTS WERE APPLIED TO OBTAIN ADDITIONAL ASSIGNMENTS AND REMARK 210 TO ASSIGN INTER-MOLECULAR NOES. FOR FURTHER DETAILS SEE THE REMARK 210 REFERENCE DESCRIBING THE STRUCTURES.
