Figure 3
500 MHz NOESY spectrum (mixing time = 300 ms) of a lysozyme crystal grown on film: He1/Hd1 and He1/Hz2 correlation of tryptophans (above). If we compare this region with the same range observed by Kristiansen et al. (1998) (below), we can observe some differences in the resonance positions of tryptophans aromatic H atoms, indicating small conformational differences between the two analysed proteins. |
