3D Complex is a hierarchical classification of protein complexes that describes similarities in structure, sequence, as well as topology of contacts of the constituent proteins. This is the first automatic method for generating non-redundant sets of complexes, which can be used to derive unbiased statistics on their structure and evolution.

Main features of this server
Through this Web Server, you can:
- Browse the classification of protein complexes,
- Search for protein complexes according various attributes,
- Download non-rednundant sets of protein complexes (e.g. all hetero- or homodimers in PDB) at various similarity thresholds,
3D Complex v2.0 Several features have been added in this new release!
- Generally, the back-end has been extensively re-worked to provide you with more frequent updates.
- SCOP 1.73 has been incorporated, yielding 10,000 additional structures and a total of over 30,000 structures.
- PiQSi is now fully integrated so you can download non-redundant sets where erroneous Biological Units are filtered out.
- Roll over a graph image and a menu will pop-up, which allows you, to search in one click all structures containing a similar complex, chain, or domain to the one you selected.
- The definition of the hierarchy has been revised to provide more accurate non-redundant sets. We recommend you to look at the documentation of this release for more details.
- Finally, you can try the improved Quick Search:
