NMR analysis of trpzip4. (A) Overlay of the COSY fingerprint regions for the wild-type gb1 peptide (red) and trpzip4 (black); the location of crosspeaks are indicated for both peptides and are labeled for trpzip4. (B) Ensemble of 20 structures of trpzip 4 compared with the minimized mean structure of the B1 domain of protein G (Protein Data Bank code 2GB1) (30); backbone atoms of protein residues 46–52 were superposed on the mean coordinates of the ensemble, yielding a rmsd of 0.67 Å.
