Molecular Docking & Interaction Simulation Service

Molecular docking and interaction simulation are foundational computational techniques in structural biology, chemical biology, and drug discovery, designed to predict and analyze the binding behavior between biomolecules—most commonly a macromolecular "receptor" (such as a protein, DNA, or RNA) and a smaller "ligand" (including small molecules, peptides, or other biopolymers). At its core, molecular docking addresses an optimization problem: identifying the most energetically favorable orientation (binding mode or "pose") of a ligand within a receptor's binding pocket, while quantifying the strength of their association (binding affinity) through specialized scoring systems. Unlike static experimental techniques that capture a single snapshot of molecular interactions, interaction simulation—predominantly molecular dynamics (MD) simulation—provides a dynamic, time-resolved view of how these biomolecules behave once bound, tracking atomic movements over femtosecond to nanosecond time scales to reveal conformational changes, interaction stability, and environmental influences on binding.

Protein-small molecule docking for drug discovery and ligand screening.

Protein-Small Molecule Docking Services

We provide protein-small molecule docking services optimized for structure-based drug discovery and small molecule research, the most widely used application of molecular docking in scientific research. These services include high-throughput virtual screening (HTVS) of large compound libraries (up to millions of compounds) to identify potential ligands that bind to a target protein, induced-fit docking to account for receptor flexibility, and covalent docking for irreversible inhibitors—critical for targeting enzymes with active-site nucleophilic residues. We also offer binding affinity prediction and pose ranking, using advanced scoring functions and machine learning enhancements to prioritize the most promising ligand candidates for experimental validation.

Protein-protein docking to study macromolecular interactions.

Protein-Protein Docking Services

We offer specialized docking services for studying macromolecular interactions, including protein-protein and protein-nucleic acid (DNA/RNA) docking—critical for understanding fundamental biological processes such as cell signaling, transcription, translation, and immune response. Protein-protein docking services predict the binding interface between two or more proteins, quantify the stability of the protein complex, and analyze how mutations or post-translational modifications affect their interaction. These services are particularly valuable for studying antibody-antigen interactions, enzyme-subunit assembly, and signaling protein complexes, providing insights into disease mechanisms and potential therapeutic targets.

Docking services for protein-DNA/RNA interaction modeling.

Protein-Nucleic Acid Docking Services

Protein-nucleic acid docking services focus on modeling interactions between proteins (e.g., transcription factors, DNA repair enzymes, or viral proteins) and DNA/RNA sequences, helping researchers understand how these interactions regulate gene expression, DNA replication, and viral replication. For example, our services can model the interaction between a transcription factor and its target DNA sequence, revealing how mutations in the DNA binding domain affect gene regulation, or model the binding of viral proteins to host RNA, informing the design of RNA-targeted therapeutics.

MD simulations for dynamic molecular interaction analysis.

Molecular Dynamics (MD) Simulation Services

Our MD simulation services provide dynamic insights into molecular interactions, complementing static docking results to reveal the time-dependent behavior of biomolecular complexes. We offer a range of MD simulation services, including protein-ligand MD simulations (to study complex stability over time), membrane protein simulations (to model proteins in their native cellular membrane environment), protein folding simulations (to understand how proteins adopt their functional 3D structure), and mutation effect simulations (to predict how amino acid changes affect protein stability and ligand binding).

Our service portfolio covers the entire workflow of molecular docking and interaction simulation, from initial data preparation to detailed result analysis and visualization. We support researchers at every stage of their project, whether they are screening large compound libraries to identify lead molecules, studying protein-protein or protein-nucleic acid interactions, optimizing ligand structure for improved binding affinity, or investigating the dynamic behavior of biomolecular complexes.
