3DRobot

3DRobot generates diverse, well-packed protein structure decoys for use in protein folding simulations and force field development.

Key Features:

• Automated Decoy Generation: Automates creation of high-quality decoys for target proteins.
• Enhanced Diversity and Evenness: Produces decoys with improved diversity and an even RMSD distribution using free fragment assembly that enhances hydrogen-bonding interactions and compactness.
• Improved Hydrogen-Bonding Network: Implements new energy terms to optimize hydrogen-bonding networks and yield realistic non-native conformations not readily recognized by trivial potentials.
• Benchmarked Performance: Validated against three widely used decoy sets derived from ab initio folding and comparative modeling simulations.

Scientific Applications:

• Protein force field development: Provides diverse non-native conformations to train and validate protein force fields.
• Folding simulation benchmarking: Supplies evenly distributed decoy sets for benchmarking ab initio folding and comparative modeling methods and for studying protein dynamics and stability.

Methodology:

Generates decoys by free fragment assembly with enhanced hydrogen-bonding and compactness interactions and incorporates new energy terms to optimize hydrogen-bonding networks.
