PDBWiki
PDBWiki was a wiki that functioned as a user-contributed database of protein structure annotations, listing all the protein structures available in the Protein Data Bank (PDB). It ran on the MediaWiki wiki application from 2007 to 2013. The website went offline in 2014 and there has not been any way to subsequently access the information that was contributed. PDBWiki contained details of more than 50,000 protein structures and over 50 'user-contributed' annotations, making it a significant resource for the structural biology community.
