Fig. 2. Overlay of the fingerprint region of COSY spectra for Z38 (black) and Z34C (red). Spectra were acquired under identical conditions at 8°C (pH 5.1). Selected crosspeaks are labeled for Z34C; arrows show the location of the same crosspeak in Z38. Complete 1H resonance assignments are available from the authors upon request.
