TOPOFIT DATABASE (T-DB, release 0.9) contains 86,033,950 structural alignments between all proteins in the PDB as of July 2005 found by the TOPOFIT method. Structure neighbors to the query protein structure can be retrieved by the PDB code and chain id. Pairwise or multiple structural alignments can be visualized in 3D with the FRIEND software (T-DB pages are under construction, any comments are welcome). (example output)
