a, The whole molecule, prepared with O41. Domains D0, D1, D2, D3 and the spoke region are labelled D0, D1, D2, D3 and S, respectively. b, Magnified stereo view of the terminal chains in domain D0. The magnified area is indicated by a box in a. The atomic model of a subunit at the centre is drawn in stick representation and atoms are coloured as: carbon, yellow; nitrogen, blue; oxygen, red. The other subunits surrounding it are drawn in thin wire representation and are coloured pink. The figure was prepared with XTALVIEW45 and RASTER3D46. Contour levels of the maps are about 2sigma.
