The peptide was chemically synthesized. It is a novel sequence derived from phage-display selection.
sample
This structure was determined using standard 2D homonuclear techniques.
The sample contains a mixture of cis and trans isomers about the Gly7-Pro8 peptide bond.
Both sets of resonances were assigned.
The trans isoform is not well ordered in solution.
The cis isoform is structured, especially within the disulfide cycle.
Structures were calculated on the basis of restraints generated only from the cis isoform.

The structures are based on 52 NOE distance restraints, 11 phi and 4 chi-1 dihedral angle restraints.
No hydrogen bond restraints were employed.
The mean backbone atom RMSD to the mean structure within the disulfide cycle is 0.43 +/- 0.12 Angstoms.
