Figure 2
The molecular packing and unit cell of FW viewed along the a axis. The four independent peptide molecules in the asymmetric unit have been labeled A, B, C and D. For comparison, the structures of FF, FL (Görbitz, 2001) and WG (Emge et al., 2000; Birkedal et al., 2002) are shown on the same scale. Atoms in side chains are shown in a darker tone. |
