(a) The aliphatic region of a 2D 13C/13C correlation SSNMR spectrum and (b) sequential assignments by 3D (purple) NCOCA and (red) CANCO spectra of GB1 micro-crystal sample incubated with 30 mM Cu2+-EDTA. The data were collected at the 1H frequency of 750 MHz using the PACC approach with a recycle delay of 300 ms using a Bruker 1.3 mm CPMAS triple-resonance probe. The experimental times were (a) 15 min and (b) 1 hour for each 3D data.
