Figure 1. A, Ribbon representation of the b-ring with one bound P16 peptide. Only the seven C-terminal residues of the peptide were structured and modelled into the density map (coloured in yellow). B, Fourier difference maps around the visible part of P16 with (F[o] -F[c]) coefficients in red, and with (2F[o] -F[c]) coefficients in blue.
