Details REFINEMENT DETAILS CAN BE FOUND IN THE JRNL CITATION ABOVE. IT IS IMPOSSIBLE TO SUPERIMPOSE THE N- AND C-TERMINAL DOMAIN OF CAM SIMULTANEOUSLY DUE TO THE LACK OF NOES BETWEEN BOTH DOMAINS. THEREFOR THE 26 STRUCTURES ARE SUPERIMPOSED ONLY OVER THE BACKBONE ATOMS OF THE C-TERMINAL DOMAIN OF CAM AND THE PEPTIDE C20W. RMSD VALUES OF THE N-TERMINAL DOMAIN OF CAM (LEU A 4 - ALA A 73) ARE 0.85 (BACKBONE) AND 1.27 (HEAVY ATOMS) ANGSTROMS. RMSD VALUE FOR THE C- TERMINAL DOMAIN OF CAM AND THE PEPTIDE C20W (ILE A 85 - MET A 145, GLY B 4 - GLN B 16) ARE 0.57 (BACKBONE) AND 1.08 (HEAVY ATOMS) ANGSTROMS. RESIDUES ALA A 1 - GLN A 3, ARG A 74 - GLU A 84, THR A 146 - LYS A 148 OF CAM AND RESIDUES LEU B 1 - ARG B 3, THR B 17 - LYS B 20 OF THE PEPTIDE C20W ARE DISORDERED.

Additional NMR Experimental Information
1 THE UNLABELED PEPTIDE C20W WAS ASSIGNED USING A 12C,14N-FILTERED NOESY- EXPERIMENT. INTERMOLECULAR NOES BETWEEN 13C,15N-LABELED CALMODULIN AND THE PEPTIDE WERE MEASURED USING A 12C,14N-F2-FILTERED NOESY-HSQC EXPERIMENT
