The complex was determined using a total of 1717 NOE distance restraints
(148 intra residue, 339 sequential, 328 medium range, 699 long-range and 203 intermolecular),
36 hydrogen bond restraints,
156 dihedral angle restraints (86 phi, 44 psi and 26 chi-1)
and 82 15N residual dipolar coupling restraints.
The best 20 conformers (of 100) had no distance violations greater than 0.12A
and no dihedral angle violations greater than 3.0 degrees.
RMSD from experimental distance restraints was 0.0055+/-0.0007.
The mean backbone rmsd from the mean structure was 0.40+/- 0.05 A for N, Ca and C atoms of residues 10-100.
74% (25%) of residues were in the most favoured (allowed) region of phi/psi space;
no residues were in the disallowed region.
