Protein-Protein Docking Service

Protein-Protein Docking Service

The interaction between proteins is essential. It is the basis of all metabolic activities of the cell. In order to better understand the biological activity of cells, the function of protein monomers and complexes must be well understood, which will involve the study of protein interactions. Recognizing and studying protein-protein docking is an important research content in life sciences. Drug molecules used to treat diseases usually regulate or block protein-protein interactions, so protein-protein interaction sites also represent an important class of drug targets. Computational methods can well supplement the experimental determination of the structure of complexes when studying protein docking.

Classifications of our protein-protein docking service

Classifications Features
Bound docking

The protein structure used in the docking comes from the complex they form.

Unbound docking

The protein structure used in unbound docking comes from the monomer structure when they are not bound to other proteins in most cases. One difficulty of unbound docking is the change of protein conformation.

CD ComputaBio' protein-protein docking is the main method used in structure-based drug design. This technology is to place the ligand molecule in the position of the active site of the receptor molecule, and then in real time according to the principles of geometric complementation, energy complementation and chemical environment complementarity. Evaluate how well the ligand interacts with the receptor, and find the best binding mode between the two molecules. In drug design, the molecular docking method is mainly used to search for small molecules with good affinity with the receptor biomacromolecule from the small molecule database, and conduct pharmacological tests to discover new lead compounds.
