Cavity programs

From Proteopedia

This page lists programs that identify and offer visualization options for cavities in macromolecules. Broadly, the term "cavities" includes pockets, tunnels and channels. A pocket is a depression in the surface with one entrance. A tunnel connects two or more locations, and may or may not have entrances from the surface. Some cavities are buried with no entrances from the surface (example: 3drf).

Nearly all proteins have shallow pockets, mostly with no known functions. Some proteins have deep pockets, for example the catalytic anionic gorge in acetylcholinesterase (e. g. 1vot). Such a pocket can also be termed a tunnel accessing the catalytic site.
