Topology of the structures of gfasPurple (purple), amilCP (blue), eforRed (red) and spisPink (pink). (a) Top-down view of the tetrameric arrangement of chromoprotein monomers. The location of the chromophore (stick representation) is marked with a black arrow in molecule a. All of the molecules in the asymmetric unit are shown for eforRed and spisPink, while only four molecules in a tetrameric arrangement are shown for amilCP. Crystallographic symmetry mates are shown for the single gfasPurple molecule present in the asymmetric unit. Molecule annotations (a, b, c or d) are for illustration only and may not align with chain IDs in the PDB file. (b) Side view showing the a/b interface and (c) side view showing the a/c interface.
