Additional NMR Experimental Information
Details	THIS MODEL IS THE AVERAGE STRUCTURE OF THE ENSEMBLE OF 20 STRUCTURES (1NK2). THE UNSTRUCTURED N-TERMINAL AND C-TERMINAL AMINO ACIDS (P 101-P 107 AND P 171-P 177 IN PDB ENTRY 1NK2) WERE REMOVED PRIOR TO MINIMIZATION OF THE AVERAGE STRUCTURE BY THE MD_SCHE DULE PROGRAM OF INSIGHTII/NMR REFINE, SUBJECT TO ALL EXPERIMENTAL RESTRAINTS FOR THE DNA AND REMAINING PROTEIN RESIDUES. THE REMAINING PROTEIN RESIDUES ARE RENUMBERED STARTING WITH P 100 SO THAT THE RESIDUE NUMBERING FOLLOWS THE STANDARD, CANONICAL NUMBER ING SCHEME FOR HOMEODOMAINS.
