The structures are based on 70 NOE distance restraints, 8 phi and 3 chi-1 dihedral angle restraints.
No hydrogen bond restraints were employed.
Note that the Ha-Hb coupling constants indicate rotational averaging about the Phe4 chi-1 angle.
Several NOEs to the aromatic ring of Phe4 were not used to generate restraints as they could be satisfied
by a -60 or 180 degree rotamer, but not by both.
The mean backbone atom RMSD to the mean structure within the disulfide cycle is 0.31 +/- 0.06 Angstoms.
