The Protein-DNA Benchmark
1A73Biomolecular docking aims at predicting the structure of a complex given the three dimensional structures of its components. Although much improvement has been made in the field of protein-protein docking, in the case of protein-DNA complexes, however, progress lags behind. The scarcity of information for proper identification of interaction surfaces on DNA and its inherent flexibility have hampered the development of effective docking methods. To facilitate the development of effective protein-DNA docking methods a set of well-defined test cases that form a common ground for development, validation and comparison of docking methods is necessary.
1EYUWe present here a protein-DNA docking benchmark containing 47 unbound-unbound test cases, of which 13 are classified as easy cases, 22 as intermediate cases and 12 as difficult cases. The latter show considerable structural rearrangement upon complex formation. DNA-specific modifications such as flipped out bases and base modifications are included. The benchmark covers all major types of DNA binding proteins according to the classifications of Luscombe et al. The variety in test cases make this non-redundant benchmark a useful tool for comparison and further development of protein-DNA docking methods.
1KSYWe developed the protein-DNA benchmark to be of general use to the docking community. We welcome all suggestions aimed at improving or expanding the benchmark. You can email suggestions to Alexandre M.J.J. Bonvin.

Benchmark Download and Version History
Updates for the protein-DNA benchmark they will be posted here.
  • 01-01-2008 | The original protein-DNA benchmark version 1.0 release. You can download a gziped version of the benchmark here.
  • 14-08-2008 | Benchmark version 1.1: Minor updates. The bound to unbound residue mapping file (profit.dat) has been redesigned to make it more flexible in use. The PDB structure file that represents the complex reconstructed from the unbound processed components after superimposition contained more than one instance of the same complex coordinate set. This has been fixed. You can download a gziped version of benchmark version 1.1 here
  • 22-09-2009 | Benchmark version 1.2: Small fixes in residue mapping for two entries. For two entries (1EYU,1RVA) the unbound protein was composed off two distinct subunits. These have now been separated into individual pdb files and all other files have been adjusted accordingly. You can download a gzipped version of benchmark version 1.2 here
  • 02-05-2013 | Benchamrk version 1.3: Merged version 1.2 with the benchmark compiled for the solvated protein-DNA docking study. You can download a gzipped version of benchmark version 1.3 here
