Backgroud
Predicting hot spot sites on proteins is a challenging task that requires advanced computational methods. Computational modeling offers a powerful tool for predicting hot spot sites by simulating the interaction between proteins and ligands or other proteins at the atomic level. By analyzing the interaction energies and structural features of the protein-ligand complex, computational models can identify the regions on the protein surface that are most likely to be involved in the interaction.

Description
Hot Spot Site Prediction for Protein-Protein Interactions
We use computational modeling to predict the hot spot sites on proteins involved in protein-protein interactions. Our models take into account the structural and energetic properties of the protein-protein complex to identify the regions that are most likely to be involved in the interaction. This information can be used to design inhibitors or modulators of protein-protein interactions for therapeutic or research purposes.
Hot Spot Site Prediction for Protein-Ligand Interactions
We also offer hot spot site prediction services for protein-ligand interactions. Our computational models analyze the binding mode and interaction energies between the protein and ligand to identify the hot spot sites on the protein surface. This information can be used to design more effective drugs or ligands that target specific regions on the protein.
Hot Spot Site Validation and Experimental Design
In addition to predicting hot spot sites, we also offer services to validate and experimentally test our predictions. We can design and perform experiments, such as site-directed mutagenesis or binding assays, to confirm the presence of hot spot sites and measure their contribution to the interaction. This provides valuable feedback for refining our computational models and improving the accuracy of our predictions.
