Multi-Conformer Ensemble Docking to Difficult Protein Targets
JOURNAL OF PHYSICAL CHEMISTRY B, 119:1026-1034, JAN 22 2015
Large-scale ensemble docking is investigated using five proteins from the Directory Of Useful' Decoys (DUD, ducl.clocking.org) for which docking to crystal structures has proven difficult. Molecular dynamics trajectories are produced for each protein, and an ensemble of representative conformational structures extracted from the trajectories. Docking calculations are performed on these selected simulation structures and ensemble-based enrichment factors compared with those obtained using docking in crystal structures of the same protein targets or random selection of compounds. Simulation-derived snapshots are found with improved enrichment factors that increase the chemical diversity of docking hits for four of the five selected proteins. A combination of all the docking results obtained from moleCtilar dynamics simulation followed by selection of top-ranking compounds appears to be an effective strategy for increasing the number and diversity of hits when using docking to screen large libraries of chemicals against difficult protein targets.
