QUASIPROX
Quaternary Structure Inference of Proteins from their Crystals

This page provides downloads of data sets and software in conjunction with the following publications:

H. Ponstingl, T. Kabir & J. M. Thornton (2003) Automatic inference of protein quaternary structure from crystals, J. Appl. Cryst. 36, 1116-1122.

H. Ponstingl, K. Henrick & J. M. Thornton (2000) Discriminating between homodimeric and monomeric proteins in the crystalline state. Proteins 41, 47-57.

Data sets:

Monomeric proteins

crystals which contain possible self-assemblies with point group symmetry ("closed" assemblies)
crystals which contain only screw axes (or pure translational symmetry) and, therefore, no self-assembly with point group symmetry.

Homomeric proteins
Heteromeric proteins

Software:

PITA (Protein InTerfaces & Assemblies) software as gzipped tar file.
