Mapping the surface hydrophobicity of chymotrypsin: A half-section of the chymotrypsin protein (PDB ID: 2ea3) in 3-D is shown on the left, as a surface point cloud, color-coded by hydrophobic (orange) and hydrophilic (gray) regions, and active site (red). A 2-D mapping of chymotrypsin half-section using Sammon mapping is shown on the right.
