Dimer packing and superposition of wild-type Agp2-PCM and Agp2-PAiRFP2. In a, b, the crystallographically related monomers in the asymmetric unit are shown for a wild-type Agp2-PCM (parallel dimer) in blue and grey colour and b for Agp2-PAiRFP2 in orange and grey colour. c Symmetry-related crystallographic dimer (anti-parallel dimer) for Agp2-PAiRFP2 (Mol B - grey; Mol B-Sym - red). d A superimposition is shown for Mol A monomers of both crystal structures (wild-type Agp2-PCM - blue; Agp2-PAiRFP2 - orange), which reveal the high structural similarity of both crystal structures. All protein monomers are displayed as ribbons
