Proteopedia is a wiki, 3D encyclopedia of proteins and other molecules.
The site contains a page for every entry in the Protein Data Bank (>130,000 pages), as well as pages that are more descriptive of protein structures in general such as acetylcholinesterase, hemoglobin, and the photosystem II with a Jmol view that highlights functional sites and ligands. It employs a scene-authoring tool so that users do not have to learn JSmol script language to create customized molecular scenes. Custom scenes are easily attached to "green links" in descriptive text that display those scenes in JSmol. A web browser is all that is needed to access the site and the 3D information; no viewers are required to be installed.
Proteopedia was the winner of the 2010 award for the best website by The Scientist magazine.
All user-added content is free and covered by the GNU Free Documentation License. Proteopedia is hosted at the Israel Structural Proteomics Center at the Weizmann Institute of Science.

Cryogenic electron microscopy (cryo-EM) is a cryomicroscopy technique applied on samples cooled to cryogenic temperatures. For biological specimens, the structure is preserved by embedding in an environment of vitreous ice. An aqueous sample solution is applied to a grid-mesh and plunge-frozen in liquid ethane or a mixture of liquid ethane and propane. While development of the technique began in the 1970s, recent advances in detector technology and software algorithms have allowed for the determination of biomolecular structures at near-atomic resolution.
The Protein Data Bank (PDB) is a database for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids. The data, typically obtained by X-ray crystallography, NMR spectroscopy, or, increasingly, cryo-electron microscopy, and submitted by biologists and biochemists from around the world, are freely accessible on the Internet via the websites of its member organisations (PDBe, PDBj, RCSB, and BMRB). The PDB is overseen by an organization called the Worldwide Protein Data Bank, wwPDB.
