Method SIMULATED ANNEALING PROTOCOL IN X-PLOR 3.1 WAS CARRIED OUT TO OBTAIN 25 STRUCTURES. MINIMIZED MEAN STRUCTURE OF THEM WAS FURTHER REVISED BY A 300 PS RESTRAINED MOLECULAR DYNAMICAL CALCULATION IN THE PRESENCE OF APPROXIMATELY 5000 TIP3P WATER MOLSCULES, USING CORNELL FORCE FIELD IN AMBER 4.1. THE MEAN CO-ORDINATE OF 200 STRUCTURES OBTAINED AFTER THE EQUILIBRIUM (100 PS) WAS ENERGY-MINIMIZED.

Additional NMR Experimental Information
1 SIGNALS DUE TO PROTEINS WERE OBTAINED BY NOESY, TOCSY, DQF-COSY FOR UNLABELED SAMPLE AND 1H-15N HSQC, 3D 1H-15N NOESY-HMQC AND 3D 1H-15N TOCSY-HMQC FOR THE SAMPLE WITH 15N-LABELED PROTEIN. SIGNALS DUE TO DNA WERE OBTAINED BY NOESY, TOCSY, AND DQF-COSY FOR UNLABELED SAMPLE AND 13C,15N-FILTERED NOESY FOR SAMPLE WITH 13C, 15N-LABELED PROTEIN. INTERMOLECULAR NOES WERE IDENTIFIED USING NOESY SPECTRA INCLUDING THOSE WITH AND WITHOUT 13C- OR 15N-DECOUPLING FOR SAMPLE WITH 13C,15N-LABELED PROTEIN.
