HSYMDOCK

HSYMDOCK models symmetric homo-oligomeric protein complexes to predict arrangements exhibiting Cn and Dn symmetry for structural analysis.

Key Features:

• Symmetry Support: Supports docking for both Cn and Dn symmetries of homo-oligomers.
• Hierarchical Docking Algorithm: Employs a hierarchical symmetric docking algorithm to improve modeling accuracy and computational efficiency.
• Input Flexibility: Accepts either the structure or the sequence of a subunit molecule as input.
• Symmetry Prediction: Provides automatic prediction of the complex symmetry type in addition to allowing explicit specification.
• Performance and Evaluation: Demonstrated superior performance on benchmarks including 20 CASP11-CAPRI30 homo-oligomer targets, a symmetric docking benchmark of 213 Cn and 35 Dn targets, and a nonredundant test set of 55 transmembrane proteins.
• Efficiency: Typical docking runs complete in approximately 10 to 20 minutes per job.

Scientific Applications:

• Homo-oligomer modeling: Modeling the quaternary structures of homo-oligomeric protein complexes exhibiting Cn or Dn symmetry.
• Transmembrane protein oligomerization: Analyzing oligomeric arrangements of transmembrane proteins using benchmarked docking protocols.
• Mechanistic studies of symmetric interactions: Elucidating molecular architectures and interaction interfaces mediated by symmetric protein assemblies.

Methodology:

Uses a hierarchical symmetric docking algorithm with systematic exploration of docking configurations, accepts structure or sequence inputs, and includes automatic symmetry-type prediction to optimize speed and accuracy.
