Figure 3. Packing of trimeric and tetrameric DAP12-TM complexes in LCP crystals.
For the trimer (A) and tetramer (B), one asymmetric unit is shown in magenta, and symmetry mates are colored by B-factor. In (C) and (D) the zoom regions are shown as 2mFo-DFc maps (sigma level 1.0; gray) and mFo-DFc maps (sigma level 3.0, green; sigma level −3.0, red) of the poorly ordered space between layers of packed helices.
