[edit] Database Description

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 annotation of ~10,000 structures of PDB Biological Units, of which about 15% were found to be likely errors.

Please, register and participate to the quaternary state annotation of PDB structures!
