Visualizing the Structure of Protein

The picture on the left is the x-ray diffraction pattern of an apilopoprotein E3 protein crystal, which plays a major role in cholesterol metabolism. The tiny spots are the x-ray reflections from the crystal, which are used to reconstruct the electron density of atoms (right).

Next Stage - The Structure Model

The colored sticks are the detailed 3-dimensional structure models of the molecule that were fitted into the actual electron density (blue grid-like areas). This stereo image appears 3D when viewed cross-eyed.

The Final Ribbon Model

Using visualization techniques, the overall 3D four-helix bundle structure of the molecule is represented as a ribbon model. The 3D image of this molecule helps researchers better understand it and its interaction with other molecules.
