PROGRAMS WRITTEN BY MICHAEL NILGES FOR SYMMETRIC DIMERS WERE USED (NILGES, M. PROTEINS 17, 297-309 (1993)). STRUCTURES WERE STARTED FROM AN EXTENDED MONOMER CONFORMATION AND RANDOM ROTATIONS WERE MADE AROUND THE PHI-PSI ANGLES. THE MONOMER WAS THEN DUPLICATED AND MOLECULAR DYNAMICS WAS PERFORMED USING NMR DISTANCE RESTRAINTS AND GENERATED SYMMETRY DISTANCE RESTRAINTS. RMSD CALCULATED BY SUPERIMPOSING STRUCTURES ON LOWEST ENERGY STRUCTURE FOR RESIDUES 33-62 OF EACH MONOMER AND 68-98 OF EACH DIMER. RMSD (ANGSTROMS): ATOMS FOR RESIDUES 33-62: 0.55 ATOMS FOR RESIDUES 33-62: 1.1 BACKBONE ATOMS FOR RESIDUES 68-98: 0.7 HEAVY ATOMS FOR RESIDUES 68-98: 1.5 |
