The basic idea is to perform ab initio folding using a lattice protein model, SICHO, near the template provided by the new threading algorithm PROSPECTOR. PROSPECTOR also provides predicted contacts and secondary structure for the template-aligned regions, and possibly for the unaligned regions by garnering additional information from other top-scoring threaded structures. Since the lowest-energy structure generated by the simulations is not necessarily the best structure, we employed two structure-selection protocols: distance geometry and clustering. In general, clustering is found to generate somewhat better quality structures in 38 of 68 cases. When applied to the Fischer database, the protocol does no harm and in a significant number of cases improves upon the initial threading model, sometimes dramatically. The procedure is readily automated and can be implemented on a genomic scale.}, keywords = {Algorithms, Chemical, Combinatorial Chemistry Techniques, Combinatorial Chemistry Techniques: methods, Computational Biology, Computational Biology: methods, Computer Simulation, Databases, Factual, Models, Molecular, Monte Carlo Method, Protein Folding, Proteins, Proteins: chemistry, Sequence Alignment, Sequence Alignment: methods}, issn = {0887-3585}, url = {http://www.ncbi.nlm.nih.gov/pubmed/11391776}, author = {Andrzej Koli{\'n}ski and Marcos Betancourt and Daisuke Kihara and Piotr Rotkiewicz and Jeffrey Skolnick} }
