===Probable Quaternary Structure Server (PQS)===
===Probable Quaternary Structure Server (PQS)===


The [http://pqs.ebi.ac.uk Probable Quaternary Structure Server]] (PQS) at the European Bioinformatics Institute examines the contacts within protein crystals, and makes an educated guess about which represent co-evolved specific oligomeric contacts, and which are artifacts of crystallization. It returns models for what it deduces to be the biological units. There are many possible relationships between the asymmetric unit and the biological units returned by PQS. Examples are given in the discussion of [http://proteinexplorer.org/pqs.htm PQS at ProteinExplorer.Org].
