Rosetta FlexPepDock

Rosetta FlexPepDock refines peptide-protein complex models at high resolution to characterize peptide conformations and interactions within protein binding sites.

Key Features:

• High-Resolution Docking Protocol: Implements a refined docking and refinement protocol within the Rosetta framework to achieve high-resolution modeling of peptide-protein complexes.
• Full Peptide Flexibility: Permits full flexibility of the peptide backbone and all side chains to accurately refine peptide conformations in binding sites.

Scientific Applications:

• Peptide-Protein Complex Refinement: Refines starting conformations to near-native accuracy, particularly effective for models within 5.5 Å backbone root mean square deviation from the native conformation.
• Study of Peptide-Regulated Systems: Applied to investigate molecular mechanisms and systems regulated by peptide-protein interactions.
• Benchmarking and Validation: Used for benchmarking docking performance against diverse, non-redundant peptide-protein complex datasets.

Methodology:

Starts from a given protein receptor structure and an initial peptide model in the binding site, then applies iterative refinement within the Rosetta framework allowing full peptide backbone and side-chain flexibility and is benchmarked against a diverse set of non-redundant peptide-protein complexes.
