REMARK 210 SOFTWARE USED : NMRPIPE 2.1, NMRVIEW 5.0.3, CNS REMARK 210 1.1 REMARK 210 METHOD USED : THE STRUCTURE OF THE COMPLEX WAS REMARK 210 CALCULATED AS FOLLOWS. FIRST THE REMARK 210 STRUCTURE OF THE DIMERIC LACHP62- REMARK 210 V52C WAS CALCULATED USING ONLY REMARK 210 PROTEIN NMR RESTRAINTS. THE 100 REMARK 210 BEST STRUCTURES WERE SELECTED REMARK 210 AND DOCKED ONTO THE NONSPECIFIC REMARK 210 LAC OPERATOR B-DNA USING REMARK 210 SIMULATED ANNEALING. DISTANCE REMARK 210 AND PLANARITY RESTRAINTS FOR THE REMARK 210 DNA WERE INCORPORATED IN ORDER REMARK 210 TO KEEP DNA CLOSE TO B-DNA REMARK 210 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 AND REMARK 210 UNLABELED NUCLEOTIDE WERE USED. IN ADDITION ISOTOPE FILTER REMARK 210 EXPERIMENTS WERE APPLIED TO OBTAIN ADDITIONAL ASSIGNMENTS AND TO REMARK 210 ASSIGN INTER-MOLECULAR NOES. FOR FURTHER DETAILS SEE THE REMARK 210 REFERENCE DESCRIBING THE STRUCTURES. REMARK 215 REMARK 215 NMR STUDY REMARK 215 THE COORDINATES IN THIS ENTRY WERE GENERATED FROM SOLUTION REMARK 215 NMR DATA. PROTEIN DATA BANK CONVENTIONS REQUIRE THAT REMARK 215 CRYST1 AND SCALE RECORDS BE INCLUDED, BUT THE VALUES ON REMARK 215 THESE RECORDS ARE MEANINGLESS.
