3D Complex is a hierarchical classification of protein complexes that describes similarities in structure, sequence, as well as the 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.
PiQSi is a community effort that facilitates the investigation and curation of quaternary structures. Given a PDB identifier or a protein sequence, it displays information about the quaternary structure of homologous proteins on a single web-page. This information allows a quick comparison of the quaternary structure(s) of the members of a protein family. So far, the web-server has allowed the manual curation of ~15000 structures of PDB Biological Units, of which about 15% were found to be likely errors (e.g. guilty).
