FlexDock

FlexDock performs flexible protein–protein docking that explicitly models large-scale conformational changes by automatically identifying hinge regions and rigid parts using HingeProt to predict association complex structures.

Key Features:

• Hinge identification (HingeProt): Uses HingeProt to detect hinge regions and rigid parts within protein structures.
• Flexible docking with large-scale motion: Performs docking simulations that explicitly consider movements around identified hinge regions to accommodate large conformational changes.
• Automated execution: Automates the detection of structural features and the execution of subsequent flexible docking computations.
• Association complex prediction: Predicts the structure of the association complex formed between interacting molecules while accounting for structural rearrangements.

Scientific Applications:

• Structural biology: Modeling protein interactions that involve large-scale conformational changes.
• Drug discovery: Aiding structure-based design of therapeutics where partner flexibility affects binding.
• Molecular mechanism studies: Improving understanding of biological interaction mechanisms by providing more accurate models when large conformational changes occur.

Methodology:

FlexDock uses HingeProt to detect hinge regions and rigid parts, then performs docking simulations that explicitly consider movements around those hinge regions to model large-scale conformational changes, and executes these steps in an automated workflow.
