Protein Surface Characterization Using an Invariant Descriptor

Figure 1

Protein structures for a sample protein (PDB id: 2UDI). (a) Secondary structure elements—α-helixes (magenta), β-sheets (gold), and turns (gray); (b) two chains: chain E (blue), chain I (green); (c) surface and 3D shape for chain E; (d) surface and 3D shape for chain I; (e) quaternary structure for the protein.
