Method torsion angle dynamics/ simulated annealing
Details The ten structures were determined by NMR and torsion angle dynamics/simulated annealing methods. The peptide dimer was treated as a single entity and symmetry elements were not utilized during structure calculations. The structures are based on a total of 446 restraints, 398 are NOE-derived distance constraints,48 distance restraints are from hydrogen bonds. The list of constraints is available in the file dyana_upperconst.txt. Structure calculations were performed with the program DYANA-1.5 (P. Guentert, C. Mumenthaler, K. Wuthrich, J. Mol. Biol.(1997)Vol.273, 283-298). No violation of distance constraints from NOEs exceeded 0.3Angstroms. The ensemble of structures is superimposed over the best-structured region encompasing residues E11-L34. The average RMSDs between the superposed structures and the average structure are as follows: 0.75(chain A, residues 11-34, backbone atoms) 0.72(chain B, residues 11-34, backbone atoms.
