Figure 1.
Figure 1 Schematic view of the Dau c 1 dimer with residual density (F[o] - F[c] map) contoured at 2.8 . The four monomers, A-D, associate into two virtually identical dimers AB (gold and green) and CD (not shown). The additional electron density observed in the hydrophobic cavity of each monomer was tentatively modelled with molecules of polyethylene glycol. The view in (b) is rotated around the horizontal axis by 90° with respect to the view in (a).
