torsion angle dynamics | The structures are based on a total of 1100 conformationally-restricting NOE-derived distance restraints, 185 dihedral angle restraints, and 28 hydrogen bond restraints.(14.8 constraints per residue; 4.4 long-range constraints per residue). Structure Determination was performed iterativly using AutoStructure (XPLOR). The constrain file for this entry was updated to correspond to the XPLOR format on September 28, 2004. | VNMR |

Details | The structure was determined using triple-resonance nmr spectroscopy. All Automatic analysis software was run out of the SPINS software. Automatic backbone resonance assignments were made using autoassign. automatic noesy assignments as well as distance and hydrogen bond restraints were determined using hyper and talos. |
