Figure 1
Residual Fourier maps calculated on an absolute scale. IAS are shown as small spheres in magenta (IAS with positive occupancy) and in brown (IAS with negative occupancy). (a, b) Maps at 0.43 Å resolution for YGG. Left and middle, IAM-phased maps; right, IAM–IAS-phased maps. Contour colours are +0.20 e Å−3 (marine), +0.10 e Å−3 (cyan), −0.10 e Å−3 (yellow) and −0.20 e Å−3 (red). Views are similar to those in Figs. 2 and 3 of Volkov et al. (2007  ). (c) Maps at 0.62 Å resolution for the antifreeze protein RD1. Left and middle, IAM-phased maps shown at cutoff levels of 0.40 e Å−3 (green) and 0.25 e Å−3 (light blue); right, IAM–IAS-phased map shown at a cutoff level of 0.25 e Å−3 (light blue). The sulfate ion inserted instead of the previously located water nicely fits the residual density (shown in brown). |
