Rotamers are low-energy conformations of side-chain dihedral angles. Only a small number of rotamer states and combinations are significantly populated in natural proteins. This tremendously simplifies protein structure modelling and prediction problems. However it also guides analysis, e.g. in enzyme active sites the rotamers often exist in strained, rare conformations.

Surfaces represent the parts of a protein that interact with the surroundings. In this example, the electrostatic potential mapping shows how an electrostatic potential gradient attracts the substrate molecule into Acetylcholine-esterase's active site.

The "Accessible Surface" depends on the probe radius. For solvent accessible surfaces a probe radius of 1.4A is commonly used since this approximates the radius of a water-molecule.
