Projection of the power spectrum [|G_{{\hat {\bf n}}}(\nu)|^2] (a) and section [|G_{{\hat  {\bf n}}}({\overline \nu})|^2] (b) in the plane (t, [varphi]) for 2qu5 . The boxes are centred on the [alpha]-helix directions calculated from the published coordinates for the [alpha]-[beta] (blue) and mainly [alpha] (red) domains. The lengths of their sides are equal to the steps used to define the grid. Dashed lines indicate the restriction introduced by the space-group symmetry.  [article HTML]
