3D Print and Structural Features of Ferritin
Ferritin is a spherical protein made up of 24 identical chains. The chains form two different types of channels: 3-fold channels, used for iron transport (Image 1) and 4-fold channels used for transport of other atoms (Image 2).
On the inside, ferritin forms a hollow shell that stores iron for future use. Small beads can be used to model the iron ions stored inside the shell (Image 3).
Double-sided tape was used to connect the half-spheres together. Alternatively, small magnets could be inserted after drilling holes in the model.
