DISTANCE GEOMETRY (DGII INTERFACED TO INSIGHTII) FOLLOWED BY OPTIMIZATION USING SIMULATED ANNEALING WITHOUT A PHYSICAL FORCEFIELD WAS USED TO GENERATE 39 STARTING STRUCTURES. THESE 39 STRUCTURES WERE FURTHER REFINED BY RESTRAINED MOLECULAR DYNAMICS AND RESTRAINED MINIMIZATION USING DISCOVER AND THE AMBER FORCEFIELD. THE 20 BEST STRUCTURES WITH LOWEST ENERGY AND FEWEST ABERRATIONS IN WELL-DEFINED REGIONS WERE SELECTED. RESTRAINTS INCLUDE 1336 INTERRESIDUE NOES, 55 PHI TORSION RESTRAINTS, 42 HYDROGEN BONDS, 15 METAL TO LIGAND DISTANCES, AND PEPTIDE BOND TORSION RESTRAINTS TO MAINTAIN PLANARITY. THE COMPLETE RESTRAINT LIST IS AVAILABLE AS PDB ENTRY 1UMT-MR. THE MEAN LARGEST NOE VIOLATION IS 0.64 +/- 0.07 ANGSTROM. FOR RESIDUES 83 THROUGH 250, THE MEAN BACKBONE (N, CA, C', O) RMSD TO THE AVERAGE IS 0.91 +/- 0.06 ANGSTROM. THE MEAN RMSD OF ALL HEAVY ATOMS TO THE AVERAGE IS 1.42 +/- 0.06 ANGSTROM. THIS ENSEMBLE WAS AVERAGED AND MINIMIZED WITH RESTRAINTS TO GENERATE THIS MODEL. RESIDUES 249 (167) - 256 (174) AT THE C-TERMINUS ARE DYNAMICALLY DISORDERED IN SOLUTION, JUDGING FROM THEIR LONG T2S AND LACK OF NOES. THESE RESIDUES HAVE BEEN OMITTED FROM THE MODEL.Felix
