Figure 5
Representation of the Patterson self-rotation function of the set of structure factors in space group P3 for α-LA (using a spherical integration radius of 21 Å and data between 8 and 4.5 Å resolution) was produced using GLRF (Tong & Rossmann, 1990BB24). The diagram indicates the presence of a strong twofold along the crystallographic c axis (ψ = 90, φ = 90, κ = 180°), as is usually expected for a crystallographic sixfold axis. Additionally, twofold peaks occur every 30° in the ab plane. The total number of peaks is 12 and this would suggest an erroneously high space group of the P6/mmm Laue family with 12 copies of the asymmetric unit in the unit cell (for a nice discussion on the interpretation of peaks in the Patterson self-rotation function in the case of human lactoferrin, see Breyer et al., 1999BB1).
