Macromolecule Design and Analysis
Comprehensive Portfolio of Validated Scientific Tools for Every Aspect of Macromolecule-based Research
Enhance Macromolecule-Based Research
Determining the three-dimensional structure and properties of macromolecules, such as enzymes and antibodies, is a fundamental component to a wide range of research activities. For example, different conformations which arise from normal molecular dynamics or interactions with ligands or other proteins may reveal novel binding sites or provide clues as to its function. While thousands of molecules have had their structures resolved experimentally, obtaining high fidelity structural data remains a nontrivial process.
Simulation can augment physical experimentation by providing insight into macromolecular structure. Additionally, techniques such as homology modeling can help predict structural models for novel molecules, guiding therapeutic design and protein engineering efforts. BIOVIA Discovery Studio delivers a comprehensive portfolio of market leading, validated scientific tools, able to assist in every aspect of macromolecule-based research.

Model
- Analyze and prepare structures from 3D structure repositories (e.g., PDB)
- Generate 3D structure models using MODELER
- Verify the quality of a structure model
- Use LOOPER to systematically search loop conformations and rank using CHARMm
- Graft loop conformations from a template structure onto a target model
- Systematically optimize amino acid side-chains using ChiRotor CHARMm simulations
- Use ZDOCK to perform protein-protein docking and examine binding partner interactions
- Study conformational flexibility with explicit solvent-based Molecular Dynamics (MD) simulations using CHARMm or NAMD
Design
- Predict electrical properties of the protein, including pH-dependent stability and protonation states and the isoelectric point
- Conduct thermal or pH-based mutational stability and binding affinity predictions
- Identify potential stable disulfide bridge locations
- Calculate biophysical properties important for protein formulation, including viscosity and solubility
