PQS Summary

Assemblies are generated using the Protein Quaternary Structure server (PQS). PQS uses crystal symmetry matrices to generate symmetry-related copies of the chains in a PDB entry and, by considering the buried surface area between pairs of chains, determines the likelihood of that contact being of some biological significance. The full algorithm is described here.
