Flexible Peptide Docking

Docking flexible peptides upon to a potential binding partner is performed with the Flexible Peptide Docking (FlexPepDock) framework of the Rosetta software suite [1],[2],[3]. Starting from a peptide sequence and an approximate location of the binding site, peptides can be simultaneously folded de novo and docked. The framework offers a refinement, ab initio and global docking protocol. The refinement protocol can be utilized to refine a coarse-grain model of the interaction, while ab initio additionally handles a peptide with no prior knowledge of its backbone conformation. The global docking protocol is designed for cases where not even the binding site is known. The FlexPepDock framework enables high-resolution peptide modeling and thus enables detailed structure-based studies of peptide-protein interactions.
