Figure 3. Interface residues of clathrin heavy chain.

The figure provides closer view of one of the heavy chains in the structure of clathrin coat (shown in figure 2) and its residues interacting with various components of the vesicular assembly. The clathrin heavy chain is shown in purple and clathrin light chain in yellow. The red spheres depict the residues of heavy chain interacting with other clathrin chains (either light chains or other heavy chains), pink spheres are the residues in interaction with auxillin peptide (an accessory protein) while orange spheres are the residues interacting with adaptor protein chain and the residues forming interface with amphiphysin peptide (another example of accessory protein) are in cyan.
