Figure 1
The asymmetric unit contents of the S100B–W61 crystal. (a) Two S100B homodimers and one W61 peptide are visible in the asymmetric unit. Monomers of S100B are shown in shades of green, the W61 peptide is shown in violet and Ca2+ ions are shown as black spheres. (b) Final refined 2Fo − Fc electron density (blue mesh) contoured at 1σ above the mean of the composite OMIT map shows the W61 peptide on the surface of S100B chain A in the same orientation as in (a). |
