Figure 3
Crystal packing in the wild-type and the selenomethionine-derivative mutant structures reveals a nearly identical molecular arrangement. (a) The tetrameric contents of the asymmetric unit of the wild-type native crystals are shown as a red ribbon diagram, with a tetramer related by rotational symmetry shown in blue. (b) The octameric contents of the selenomethionine-derivative mutant asymmetric unit are shown in red.  [article HTML]
