A protein-protein docking benchmark

We have developed a nonredundant benchmark for testing protein–protein docking algorithms. Currently it contains 59 test cases: 22 enzyme‐inhibitor complexes, 19 antibody‐antigen complexes, 11 other complexes, and 7 difficult test cases. Thirty‐one of the test cases, for which the unbound structures of both the receptor and ligand are available, are classified as follows: 16 enzyme‐inhibitor, 5 antibody‐antigen, 5 others, and 5 difficult. Such a centralized resource should benefit the docking community not only as a large curated test set but also as a common ground for comparing different algorithms. The benchmark is available at (http://zlab.bu.edu/∼rong/dock/benchmark.shtml). Proteins 2003;52:88–91. © 2003 Wiley‐Liss, Inc.
